1.0.0

Breaking Changes

• CodeQL package management is now generally available, and all GitHub-produced CodeQL packages have had their version numbers increased to 1.0.0.
• Removed local query variants. The results pertaining to local sources can be found using the non-local counterpart query. As an example, the results previously found by java/unvalidated-url-redirection-local can be found by java/unvalidated-url-redirection, if the local threat model is enabled. The removed queries are java/path-injection-local, java/command-line-injection-local, java/xss-local, java/sql-injection-local, java/http-response-splitting-local, java/improper-validation-of-array-construction-local, java/improper-validation-of-array-index-local, java/tainted-format-string-local, java/tainted-arithmetic-local, java/unvalidated-url-redirection-local, java/xxe-local and java/tainted-numeric-cast-local.

Minor Analysis Improvements

• The alert message for the query "Trust boundary violation" (java/trust-boundary-violation) has been updated to include a link to the remote source.
• The sanitizer of the query java/zipslip has been improved to include nodes that are safe due to having certain safe types. This reduces false positives.

0.8.16

No user-facing changes.

0.8.15

No user-facing changes.

0.8.14

Minor Analysis Improvements

• The java/unknown-javadoc-parameter now accepts @param tags that apply to the parameters of a record.

0.8.13

New Queries

• The query java/unsafe-url-forward-dispatch-load has been promoted from experimental to the main query pack as java/unvalidated-url-forward. Its results will now appear by default. This query was originally submitted as an experimental query by @haby0 and by @luchua-bc.

Major Analysis Improvements

• The java/missing-case-in-switch query now gives only a single alert for each switch statement, giving some examples of the missing cases as well as a count of how many are missing.

Minor Analysis Improvements

• Variables named tokenImage are no longer sources for the java/sensitive-log query. This is because this variable name is used in parsing code generated by JavaCC, so it causes a large number of false positive alerts.
• Added sanitizers for relative URLs, List.contains(), and checking the host of a URI to the java/ssrf and java/unvalidated-url-redirection queries.

0.8.12

No user-facing changes.

0.8.11

No user-facing changes.

0.8.10

New Queries

• Added a new query java/android/insecure-local-key-gen for finding instances of keys generated for biometric authentication in an insecure way.

Minor Analysis Improvements

• To reduce the number of false positives in the query "Insertion of sensitive information into log files" (java/sensitive-log), variables with names that contain "null" (case-insensitively) are no longer considered sources of sensitive information.

0.8.9

New Queries

• Added a new query java/android/insecure-local-authentication for finding uses of biometric authentication APIs that do not make use of a KeyStore-backed key and thus may be bypassed.

Query Metadata Changes

• The security-severity score of the query java/relative-path-command has been reduced to better adjust it to the specific conditions needed for exploitation.

Major Analysis Improvements

• The sinks of the queries java/path-injection and java/path-injection-local have been reworked. Path creation sinks have been converted to summaries instead, while sinks now are actual file read/write operations only. This has reduced the false positive ratio of both queries.

Minor Analysis Improvements

• The sanitizer for the path injection queries has been improved to handle more cases where equals is used to check an exact path match.
• The query java/unvalidated-url-redirection now sanitizes results following the same logic as the query java/ssrf. URLs where the destination cannot be controlled externally are no longer reported.

0.8.8

New Queries

• Added a new query java/android/sensitive-text to detect instances of sensitive data being exposed through text fields without being properly masked.
• Added a new query java/android/sensitive-notification to detect instances of sensitive data being exposed through Android notifications.

0.8.7

New Queries

• Added the java/exec-tainted-environment query, to detect the injection of environment variables names or values from remote input.

Minor Analysis Improvements

• A manual neutral summary model for a callable now blocks all generated summary models for that callable from having any effect.

0.8.6

New Queries

• Added the java/insecure-randomness query to detect uses of weakly random values which an attacker may be able to predict. Also added the crypto-parameter sink kind for sinks which represent the parameters and keys of cryptographic operations.

Minor Analysis Improvements

• Modified the java/potentially-weak-cryptographic-algorithm query to include the use of weak cryptographic algorithms from configuration values specified in properties files.
• The query java/android/missing-certificate-pinning should no longer alert about requests pointing to the local filesystem.
• Removed some spurious sinks related to com.opensymphony.xwork2.TextProvider.getText from the query java/ognl-injection.

Bug Fixes

• The three queries java/insufficient-key-size, java/server-side-template-injection, and java/android/implicit-pendingintents had accidentally general extension points allowing arbitrary string-based flow state. This has been fixed and the old extension points have been deprecated where possible, and otherwise updated.

0.8.5

No user-facing changes.

0.8.4

No user-facing changes.

0.8.3

Minor Analysis Improvements

• The query java/unsafe-deserialization has been improved to detect insecure calls to ObjectMessage.getObject in JMS.

0.8.2

Minor Analysis Improvements

• java/summary/lines-of-code now gives the total number of lines of Java and Kotlin code, and is the only query tagged lines-of-code. java/summary/lines-of-code-java and java/summary/lines-of-code-kotlin give the per-language counts.
• The query java/spring-disabled-csrf-protection has been improved to detect more ways of disabling CSRF in Spring.

0.8.1

Minor Analysis Improvements

• Most data flow queries that track flow from remote flow sources now use the current threat model configuration instead. This doesn't lead to any changes in the produced alerts (as the default configuration is remote flow sources) unless the threat model configuration is changed.

0.8.0

No user-facing changes.

0.7.5

No user-facing changes.

0.7.4

New Queries

• Added the java/trust-boundary-violation query to detect trust boundary violations between HTTP requests and the HTTP session. Also added the trust-boundary-violation sink kind for sinks which may cross a trust boundary, such as calls to the HttpSession#setAttribute method.

Minor Analysis Improvements

• The queries "Resolving XML external entity in user-controlled data" (java/xxe) and "Resolving XML external entity in user-controlled data from local source" (java/xxe-local) now recognize sinks in the MDHT library.

0.7.3

No user-facing changes.

0.7.2

Minor Analysis Improvements

• The sanitizer in java/potentially-weak-cryptographic-algorithm has been improved, so the query may yield additional results.

0.7.1

Minor Analysis Improvements

• The query "Unsafe resource fetching in Android WebView" (java/android/unsafe-android-webview-fetch) now recognizes WebViews where setJavascriptEnabled, setAllowFileAccess, setAllowUniversalAccessFromFileURLs, and/or setAllowFileAccessFromFileURLs are set inside the function block of the Kotlin apply function.

0.7.0

Minor Analysis Improvements

• New models have been added for org.apache.commons.lang.
• The query java/unsafe-deserialization has been updated to take into account SerialKiller, a library used to prevent deserialization of arbitrary classes.

Bug Fixes

• The query "Arbitrary file write during archive extraction ("Zip Slip")" (java/zipslip) has been renamed to "Arbitrary file access during archive extraction ("Zip Slip")."

0.6.4

No user-facing changes.

0.6.3

Minor Analysis Improvements

• The java/summary/lines-of-code query now only counts lines of Java code. The new java/summary/lines-of-code-kotlin counts lines of Kotlin code.

0.6.2

Minor Analysis Improvements

• The query java/groovy-injection now recognizes groovy.text.TemplateEngine.createTemplate as a sink.
• The queries java/xxe and java/xxe-local now recognize the second argument of calls to XPath.evaluate as a sink.
• Experimental sinks for the query "Resolving XML external entity in user-controlled data" (java/xxe) have been promoted to the main query pack. These sinks were originally submitted as part of an experimental query by @haby0.

0.6.1

No user-facing changes.

0.6.0

New Queries

• The query java/insecure-ldap-auth has been promoted from experimental to the main query pack. This query detects transmission of cleartext credentials in LDAP authentication. Insecure LDAP authentication causes sensitive information to be vulnerable to remote attackers. This query was originally submitted as an experimental query by @luchua-bc

0.5.6

No user-facing changes.

0.5.5

New Queries

• Added a new query, java/android/arbitrary-apk-installation, to detect installation of APKs from untrusted sources.

0.5.4

No user-facing changes.

0.5.3

New Queries

• Added a new query, java/xxe-local, which is a version of the XXE query that uses local sources (for example, reads from a local file).

Minor Analysis Improvements

• The java/index-out-of-bounds query has improved its handling of arrays of constant length, and may report additional results in those cases.

0.5.2

New Queries

• Added a new query, java/android/sensitive-result-receiver, to find instances of sensitive data being leaked to an untrusted ResultReceiver.

0.5.1

New Queries

• Added a new query java/android/websettings-allow-content-access to detect Android WebViews which do not disable access to content:// urls.

Minor Analysis Improvements

• The name, description and alert message for the query java/concatenated-sql-query have been altered to emphasize that the query flags the use of string concatenation to construct SQL queries, not the lack of appropriate escaping. The query's files have been renamed from SqlUnescaped.ql and SqlUnescapedLib.qll to SqlConcatenated.ql and SqlConcatenatedLib.qll respectively; in the unlikely event your custom configuration or queries refer to either of these files by name, those references will need to be adjusted. The query id remains java/concatenated-sql-query, so alerts should not be re-raised as a result of this change.

0.5.0

New Queries

• Added a new query, java/summary/generated-vs-manual-coverage, to expose metrics for the number of API endpoints covered by generated versus manual MaD models.
• Added a new query, java/telemetry/supported-external-api, to detect supported 3rd party APIs used in a codebase.
• Added a new query, java/android/missing-certificate-pinning, to find network calls where certificate pinning is not implemented.
• Added a new query, java/android-webview-addjavascriptinterface, to detect the use of addJavascriptInterface, which can lead to cross-site scripting.
• Added a new query, java/android-websettings-file-access, to detect configurations that enable file system access in Android WebViews.
• Added a new query, java/android-websettings-javascript-enabled, to detect if JavaScript execution is enabled in an Android WebView.
• The query java/regex-injection has been promoted from experimental to the main query pack. Its results will now appear by default. This query was originally submitted as an experimental query by @edvraa.

Minor Analysis Improvements

• The AlertSuppression.ql query has been updated to support the new // codeql[query-id] supression comments. These comments can be used to suppress an alert and must be placed on a blank line before the alert. In addition the legacy // lgtm and // lgtm[query-id] comments can now also be placed on the line before an alert.
• The extensible predicates for Models as Data have been renamed (the ext prefix has been removed). As an example, extSummaryModel has been renamed to summaryModel.
• The query java/misnamed-type is now enabled for Kotlin.
• The query java/non-serializable-field is now enabled for Kotlin.
• Fixed an issue in the query java/android/implicit-pendingintents by which an implicit Pending Intent marked as immutable was not correctly recognized as such.
• The query java/maven/non-https-url no longer alerts about disabled repositories.

0.4.6

Minor Analysis Improvements

• Kotlin extraction will now fail if the Kotlin version in use is at least 1.7.30. This is to ensure using an as-yet-unsupported version is noticable, rather than silently failing to extract Kotlin code and therefore producing false-negative results.

0.4.5

No user-facing changes.

0.4.4

New Queries

• The query java/insufficient-key-size has been promoted from experimental to the main query pack. Its results will now appear by default. This query was originally submitted as an experimental query by @luchua-bc.
• Added a new query, java/android/sensitive-keyboard-cache, to detect instances of sensitive information possibly being saved to the Android keyboard cache.

0.4.3

No user-facing changes.

0.4.2

New Queries

• Added a new query, java/android/incomplete-provider-permissions, to detect if an Android ContentProvider is not protected with a correct set of permissions.
• A new query "Uncontrolled data used in content resolution" (java/androd/unsafe-content-uri-resolution) has been added. This query finds paths from user-provided data to URI resolution operations in Android's ContentResolver without previous validation or sanitization.

0.4.1

New Queries

• Added a new query, java/android/webview-debugging-enabled, to detect instances of WebView debugging being enabled in production builds.

Minor Analysis Improvements

• The alert message of many queries have been changed to better follow the style guide and make the message consistent with other languages.
• PathSanitizer.qll has been promoted from experimental to the main query pack. This sanitizer was originally submitted as part of an experimental query by @luchua-bc.
• The queries java/path-injection, java/path-injection-local and java/zipslip now use the sanitizers provided by PathSanitizer.qll.

0.4.0

New Queries

• The query "Server-side template injection" (java/server-side-template-injection) has been promoted from experimental to the main query pack. This query was originally submitted as an experimental query by @porcupineyhairs.
• Added a new query, java/android/backup-enabled, to detect if Android applications allow backups.

Query Metadata Changes

• Removed the @security-severity tag from several queries not in the Security/ folder that also had missing security tags.

Minor Analysis Improvements

• The Java extractor now populates the Method relating to a MethodAccess consistently for calls using an explicit and implicit this qualifier. Previously if the method foo was inherited from a specialised generic type ParentType<String>, then an explicit call this.foo() would yield a MethodAccess whose getMethod() accessor returned the bound method ParentType<String>.foo, whereas an implicitly-qualified foo() MethodAccess's getMethod() would return the unbound method ParentType.foo. Now both scenarios produce a bound method. This means that all data-flow queries may return more results where a relevant path transits a call to such an implicitly-qualified call to a member method with a bound generic type, while queries that inspect the result of MethodAccess.getMethod() may need to tolerate bound generic methods in more circumstances. The queries java/iterator-remove-failure, java/non-static-nested-class, java/internal-representation-exposure, java/subtle-inherited-call and java/deprecated-call have been amended to properly handle calls to bound generic methods, and in some instances may now produce more results in the explicit-this case as well.
• Added taint model for arguments of java.net.URI constructors to the queries java/path-injection and java/path-injection-local.
• Added new sinks related to Android's AlarmManager to the query java/android/implicit-pendingintents.
• The alert message of many queries have been changed to make the message consistent with other languages.

0.3.4

0.3.3

New Queries

• Added a new query, java/android/implicitly-exported-component, to detect if components are implicitly exported in the Android manifest.
• A new query "Use of RSA algorithm without OAEP" (java/rsa-without-oaep) has been added. This query finds uses of RSA encryption that don't use the OAEP scheme.
• Added a new query, java/android/debuggable-attribute-enabled, to detect if the android:debuggable attribute is enabled in the Android manifest.
• The query "Using a static initialization vector for encryption" (java/static-initialization-vector) has been promoted from experimental to the main query pack. This query was originally submitted as an experimental query by @artem-smotrakov.
• A new query java/partial-path-traversal finds partial path traversal vulnerabilities resulting from incorrectly using String#startsWith to compare canonical paths.
• Added a new query, java/suspicious-regexp-range, to detect character ranges in regular expressions that seem to match too many characters.

Query Metadata Changes

• The queries java/redos and java/polynomial-redos now have a tag for CWE-1333.

Minor Analysis Improvements

• The query java/static-initialization-vector no longer requires a Cipher object to be initialized with ENCRYPT_MODE to be considered a valid sink. Also, several new sanitizers were added.
• Improved sanitizers for java/sensitive-log, which removes some false positives and improves performance a bit.

0.3.2

New Queries

• A new query "Android WebView that accepts all certificates" (java/improper-webview-certificate-validation) has been added. This query finds implementations of WebViewClients that accept all certificates in the case of an SSL error.

Major Analysis Improvements

• The query java/sensitive-log has been improved to no longer report results that are effectively duplicates due to one source flowing to another source.

Minor Analysis Improvements

• The query java/path-injection now recognises vulnerable APIs defined using the SinkModelCsv class with the create-file type. Out of the box this includes Apache Commons-IO functions, as well as any user-defined sinks.

0.3.1

0.3.0

Breaking Changes

• Contextual queries and the query libraries they depend on have been moved to the codeql/java-all package.

New Queries

• A new query "Improper verification of intent by broadcast receiver" (java/improper-intent-verification) has been added. This query finds instances of Android BroadcastReceivers that don't verify the action string of received intents when registered to receive system intents.

0.2.0

Minor Analysis Improvements

• The query java/log-injection now reports problems at the source (user-controlled data) instead of at the ultimate logging call. This was changed because user functions that wrap the ultimate logging call could result in most alerts being reported in an uninformative location.

0.1.4

0.1.3

New Queries

• Two new queries "Inefficient regular expression" (java/redos) and "Polynomial regular expression used on uncontrolled data" (java/polynomial-redos) have been added. These queries help find instances of Regular Expression Denial of Service vulnerabilities.

Minor Analysis Improvements

• Query java/sensitive-log has received several improvements.
  • It no longer considers usernames as sensitive information.
  • The conditions to consider a variable a constant (and therefore exclude it as user-provided sensitive information) have been tightened.
  • A sanitizer has been added to handle certain elements introduced by a Kotlin compiler plugin that have deceptive names.

0.1.2

Query Metadata Changes

• Query java/predictable-seed now has a tag for CWE-337.

Minor Analysis Improvements

• Query java/insecure-cookie now tolerates setting a cookie's secure flag to request.isSecure(). This means servlets that intentionally accept unencrypted connections will no longer raise an alert.
• The query java/non-https-urls has been simplified and no longer requires its sinks to be MethodAccesses.
• The logic to detect WebViews with JavaScript (and optionally file access) enabled in the query java/android/unsafe-android-webview-fetch has been improved.

0.1.1

Minor Analysis Improvements

• Query java/insecure-cookie no longer produces a false positive if cookie.setSecure(...) is called passing a constant that always equals true.

0.1.0

Query Metadata Changes

• Added the security-severity tag to several queries.

Minor Analysis Improvements

• Fixed "Local information disclosure in a temporary directory" (java/local-temp-file-or-directory-information-disclosure) to resolve false-negatives when OS isn't properly used as logical guard.
• The SwitchCase.getRuleExpression() predicate now gets expressions for case rules with an expression on the right-hand side of the arrow belonging to both SwitchStmt and SwitchExpr, and the corresponding getRuleStatement() no longer returns an ExprStmt in either case. Previously SwitchStmt and SwitchExpr behaved differently in this respect.

0.0.13

0.0.12

New Queries

• The query "Insertion of sensitive information into log files" (java/sensitive-logging) has been promoted from experimental to the main query pack. This query was originally submitted as an experimental query by @luchua-bc.

Minor Analysis Improvements

• Updated "Local information disclosure in a temporary directory" (java/local-temp-file-or-directory-information-disclosure) to remove false-positives when OS is properly used as logical guard.

0.0.11

0.0.10

Breaking Changes

• Add more classes to Netty request/response splitting. Change identification to java/netty-http-request-or-response-splitting. Identify request splitting differently from response splitting in query results. Support additional classes:
  • io.netty.handler.codec.http.CombinedHttpHeaders
  • io.netty.handler.codec.http.DefaultHttpRequest
  • io.netty.handler.codec.http.DefaultFullHttpRequest

New Queries

• A new query titled "Local information disclosure in a temporary directory" (java/local-temp-file-or-directory-information-disclosure) has been added. This query finds uses of APIs that leak potentially sensitive information to other local users via the system temporary directory. This query was originally submitted as query by @JLLeitschuh.

0.0.9

New Queries

• A new query "Cleartext storage of sensitive information using a local database on Android" (java/android/cleartext-storage-database) has been added. This query finds instances of sensitive data being stored in local databases without encryption, which may expose it to attackers or malicious applications.

0.0.8

New Queries

• A new query "Use of implicit PendingIntents" (java/android/pending-intents) has been added. This query finds implicit and mutable PendingIntents sent to an unspecified third party component, which may provide an attacker with access to internal components of the application or cause other unintended effects.
• Two new queries, "Android fragment injection" (java/android/fragment-injection) and "Android fragment injection in PreferenceActivity" (java/android/fragment-injection-preference-activity) have been added. These queries find exported Android activities that instantiate and host fragments created from user-provided data. Such activities are vulnerable to access control bypass and expose the Android application to unintended effects.
• The query "TrustManager that accepts all certificates" (java/insecure-trustmanager) has been promoted from experimental to the main query pack. Its results will now appear by default. This query was originally submitted as an experimental query by @intrigus-lgtm.
• The query "Log Injection" (java/log-injection) has been promoted from experimental to the main query pack. Its results will now appear by default. The query was originally submitted as an experimental query by @porcupineyhairs and @dellalibera.
• A new query "Intent URI permission manipulation" (java/android/intent-uri-permission-manipulation) has been added. This query finds Android components that return unmodified, received Intents to the calling applications, which can provide unintended access to internal content providers of the victim application.
• A new query "Cleartext storage of sensitive information in the Android filesystem" (java/android/cleartext-storage-filesystem) has been added. This query finds instances of sensitive data being stored in local files without encryption, which may expose it to attackers or malicious applications.
• The query "Cleartext storage of sensitive information using SharedPreferences on Android" (java/android/cleartext-storage-shared-prefs) has been promoted from experimental to the main query pack. Its results will now appear by default. This query was originally submitted as an experimental query by @luchua-bc.
• The query "Unsafe certificate trust" (java/unsafe-cert-trust) has been promoted from experimental to the main query pack. Its results will now appear by default. This query was originally submitted as an experimental query by @luchua-bc.

Query Metadata Changes

• The "Random used only once" (java/random-used-once) query no longer has a security-severity score. This has been causing some tools to categorise it as a security query, when it is more useful as a code-quality query.

0.0.7

0.0.6

0.0.5

Minor Analysis Improvements

• The java/constant-comparison query no longer raises false alerts regarding comparisons with Unicode surrogate character literals.

0.0.4
