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.

0.8.16

No user-facing changes.

0.8.15

No user-facing changes.

0.8.14

No user-facing changes.

0.8.13

Major Analysis Improvements

  • The Stored variants of some queries (cs/stored-command-line-injection, cs/web/stored-xss, cs/stored-ldap-injection, cs/xml/stored-xpath-injection, cs/second-order-sql-injection) have been removed. If you were using these queries, their results can be restored by enabling the file and database threat models in your threat model configuration.

Minor Analysis Improvements

  • The alert message of cs/wrong-compareto-signature has been changed to remove unnecessary element references.
  • Data flow queries that track flow from local flow sources now use the current threat model configuration instead. This may lead to changes in the produced alerts if the threat model configuration only uses remote flow sources. The changed queries are cs/code-injection, cs/resource-injection, cs/sql-injection, and cs/uncontrolled-format-string.

0.8.12

No user-facing changes.

0.8.11

No user-facing changes.

0.8.10

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. The changed queries are cs/code-injection, cs/command-line-injection, cs/user-controlled-bypass, cs/count-untrusted-data-external-api, cs/untrusted-data-to-external-api, cs/ldap-injection, cs/log-forging, cs/xml/missing-validation, cs/redos, cs/regex-injection, cs/resource-injection, cs/sql-injection, cs/path-injection, cs/unsafe-deserialization-untrusted-input, cs/web/unvalidated-url-redirection, cs/xml/insecure-dtd-handling, cs/xml/xpath-injection, cs/web/xss, and cs/uncontrolled-format-string.

0.8.9

Minor Analysis Improvements

  • Added sanitizers for relative URLs, List.Contains(), and checking the .Host property on an URI to the cs/web/unvalidated-url-redirection query.

0.8.8

Minor Analysis Improvements

  • Added string interpolation expressions and string.Format as possible sanitizers for the cs/web/unvalidated-url-redirection query.

0.8.7

Minor Analysis Improvements

  • Modelled additional flow steps to track flow from handler methods of a PageModel class to the corresponding Razor Page (.cshtml) file, which may result in additional results for queries such as cs/web/xss.

0.8.6

Minor Analysis Improvements

  • Fixed a Log forging false positive when using String.Replace to sanitize the input.
  • Fixed a URL redirection from remote source false positive when guarding a redirect with HttpRequestBase.IsUrlLocalToHost()

0.8.5

No user-facing changes.

0.8.4

Minor Analysis Improvements

  • Modelled additional flow steps to track flow from a View call in an MVC controller to the corresponding Razor View (.cshtml) file, which may result in additional results for queries such as cs/web/xss.

0.8.3

Minor Analysis Improvements

  • CIL extraction is now disabled by default. It is still possible to turn on CIL extraction by setting the cil extractor option to true or by setting the environment variable $CODEQL_EXTRACTOR_CSHARP_OPTION_CIL to true. This is the first step towards sun-setting the CIL extractor entirely.

0.8.2

No user-facing changes.

0.8.1

Minor Analysis Improvements

  • The cs/web/insecure-direct-object-reference and cs/web/missing-function-level-access-control have been improved to better recognize attributes on generic classes.

0.8.0

New Queries

  • Added a new query, cs/web/insecure-direct-object-reference, to find instances of missing authorization checks for resources selected by an ID parameter.

0.7.5

No user-facing changes.

0.7.4

No user-facing changes.

0.7.3

No user-facing changes.

0.7.2

No user-facing changes.

0.7.1

No user-facing changes.

0.7.0

New Queries

  • Added a new query, cs/web/missing-function-level-access-control, to find instances of missing authorization checks.

Bug Fixes

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

0.6.4

No user-facing changes.

0.6.3

No user-facing changes.

0.6.2

No user-facing changes.

0.6.1

Minor Analysis Improvements

  • Additional sinks modelling writes to unencrypted local files have been added to ExternalLocationSink, used by the cs/cleartext-storage and cs/exposure-of-sensitive-information queries.

0.6.0

Minor Analysis Improvements

  • The query cs/web/debug-binary now disregards the debug attribute in case there is a transformation that removes it.

0.5.6

No user-facing changes.

0.5.5

No user-facing changes.

0.5.4

No user-facing changes.

0.5.3

No user-facing changes.

0.5.2

No user-facing changes.

0.5.1

No user-facing changes.

0.5.0

New Queries

  • Added a new query, csharp/telemetry/supported-external-api, to detect supported 3rd party APIs used in a codebase.

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.

Bug Fixes

  • Fixes a bug where the Owin.qll framework library will look for "URI" instead of "Uri" in the OwinRequest class.

0.4.6

No user-facing changes.

0.4.5

No user-facing changes.

0.4.4

No user-facing changes.

0.4.3

No user-facing changes.

0.4.2

No user-facing changes.

0.4.1

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.

0.4.0

Minor Analysis Improvements

  • A new extractor option has been introduced for disabling CIL extraction. Either pass -Ocil=false to the codeql CLI or set the environment variable CODEQL_EXTRACTOR_CSHARP_OPTION_CIL=false.
  • The alert message of many queries have been changed to make the message consistent with other languages.

0.3.4

0.3.3

Minor Analysis Improvements

  • Parameters of delegates passed to routing endpoint calls like MapGet in ASP.NET Core are now considered remote flow sources.
  • The query cs/unsafe-deserialization-untrusted-input is not reporting on all calls of JsonConvert.DeserializeObject any longer, it only covers cases that explicitly use unsafe serialization settings.
  • Added better support for the SQLite framework in the SQL injection query.
  • File streams are now considered stored flow sources. For example, reading query elements from a file can lead to a Second Order SQL injection alert.

0.3.2

0.3.1

0.3.0

Breaking Changes

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

0.2.0

Query Metadata Changes

  • The kind query metadata was changed to diagnostic on cs/compilation-error, cs/compilation-message, cs/extraction-error, and cs/extraction-message.

Minor Analysis Improvements

  • The syntax of the (source|sink|summary)model CSV format has been changed slightly for Java and C#. A new column called provenance has been introduced, where the allowed values are manual and generated. The value used to indicate whether a model as been written by hand (manual) or create by the CSV model generator (generated).
  • All auto implemented public properties with public getters and setters on ASP.NET Core remote flow sources are now also considered to be tainted.

0.0.11

Minor Analysis Improvements

  • Casts to dynamic are excluded from the useless upcasts check (cs/useless-upcast).
  • The C# extractor now accepts an extractor option buildless, which is used to decide what type of extraction that should be performed. If true then buildless (standalone) extraction will be performed. Otherwise tracing extraction will be performed (default). The option is added via codeql database create --language=csharp -Obuildless=true ....
  • The C# extractor now accepts an extractor option trap.compression, which is used to decide the compression format for TRAP files. The legal values are brotli (default), gzip or none. The option is added via codeql database create --language=csharp -Otrap.compression=value ....

0.0.10

Query Metadata Changes

  • The precision of hardcoded credentials queries (cs/hardcoded-credentials and cs/hardcoded-connection-string-credentials) have been downgraded to medium.
