✳️ express (4.17.1 → 4.21.1) · Repo · Changelog

Security Advisories 🚨

🚨 express vulnerable to XSS via response.redirect()

Impact

In express <4.20.0, passing untrusted user input - even after sanitizing it - to response.redirect() may execute untrusted code

Patches

this issue is patched in express 4.20.0

Workarounds

users are encouraged to upgrade to the patched version of express, but otherwise can workaround this issue by making sure any untrusted inputs are safe, ideally by validating them against an explicit allowlist

Details

successful exploitation of this vector requires the following:

  1. The attacker MUST control the input to response.redirect()
  2. express MUST NOT redirect before the template appears
  3. the browser MUST NOT complete redirection before:
  4. the user MUST click on the link in the template

🚨 Express.js Open Redirect in malformed URLs

Impact

Versions of Express.js prior to 4.19.2 and pre-release alpha and beta versions before 5.0.0-beta.3 are affected by an open redirect vulnerability using malformed URLs.

When a user of Express performs a redirect using a user-provided URL Express performs an encode using encodeurl on the contents before passing it to the location header. This can cause malformed URLs to be evaluated in unexpected ways by common redirect allow list implementations in Express applications, leading to an Open Redirect via bypass of a properly implemented allow list.

The main method impacted is res.location() but this is also called from within res.redirect().

Patches

0867302
0b74695

An initial fix went out with express@4.19.0, we then patched a feature regression in 4.19.1 and added improved handling for the bypass in 4.19.2.

Workarounds

The fix for this involves pre-parsing the url string with either require('node:url').parse or new URL. These are steps you can take on your own before passing the user input string to res.location or res.redirect.

✳️ chart.js (2.9.1 → 2.9.4) · Repo

Security Advisories 🚨

🚨 Prototype pollution in chart.js

This affects the package chart.js before 2.9.4. The options parameter is not properly sanitized when it is processed. When the options are processed, the existing options (or the defaults options) are deeply merged with provided options. However, during this operation, the keys of the object being set are not checked, leading to a prototype pollution.

Release Notes

2.9.4

This is the last release of v2 and focused on fixing bugs identified in the v2.9.3 release.

Bugs Fixed

  • #7404 - Preserve prototypes when cloning. Thanks @iddings
  • #7587 - Fix docs for external moment.js. Thanks @mojoaxel
  • #7853 - Fix box recursion when dimensions are NaN. Thanks @alessandroasm
  • #7883 - Fix call stack exception when computing label sizes. Thanks @silentmatt
  • #7918 - Prevent global prototype pollution via the merge helper
  • #7920 - Use Object.create(null) as merge target, to prevent prototype pollution

2.9.3

Bug Fixes

  • #6698 Fix undefined variable
  • #6719 Don't make legend empty when fill is false

Thanks to the maintainers and collaborators for their help to improve and test Chart.js (@kurkle, @benmccann, and @etimberg).

2.9.2

Bug Fixes

  • #6641 IE11 & Edge compatible style injection
  • #6655 Backwards compatible default fill for radar charts
  • #6660 Improve clipping of line charts when border widths are large
  • #6661 When a legend item is clicked, make sure the correct item is hidden
  • #6663 Refresh package-lock file to pick up new dependency

Performance

  • #6671 Stop unnecessary line calculations

Documentation

  • #6643 Combine performance documentation sections

Release Notes

2.0.0

Changed

  • Align encoding with WHATWG URL spec (#8) be0f77b
    • Stops encoding \, ^, and |.

Important: If you are using this to encode user entered and validated URLs, upgrade to v2 immediately. It is possible to exploit \ encoding in v1. A URL can be formed that looks like http://foo.com\@bar.com, which parses as foo.com for the host, but when encodeUrl(url) will parse as bar.com for the host.

↗️ path-to-regexp (indirect, 0.1.7 → 0.1.10) · Repo · Changelog

Security Advisories 🚨

🚨 path-to-regexp outputs backtracking regular expressions

Impact

A bad regular expression is generated any time you have two parameters within a single segment, separated by something that is not a period (.). For example, /:a-:b.

Patches

For users of 0.1, upgrade to 0.1.10. All other users should upgrade to 8.0.0.

These versions add backtrack protection when a custom regex pattern is not provided:

They do not protect against vulnerable user supplied capture groups. Protecting against explicit user patterns is out of scope for old versions and not considered a vulnerability.

Version 7.1.0 can enable strict: true and get an error when the regular expression might be bad.

Version 8.0.0 removes the features that can cause a ReDoS.

Workarounds

All versions can be patched by providing a custom regular expression for parameters after the first in a single segment. As long as the custom regular expression does not match the text before the parameter, you will be safe. For example, change /:a-:b to /:a-:b([^-/]+).

If paths cannot be rewritten and versions cannot be upgraded, another alternative is to limit the URL length. For example, halving the attack string improves performance by 4x faster.

Details

Using /:a-:b will produce the regular expression /^\/([^\/]+?)-([^\/]+?)\/?$/. This can be exploited by a path such as /a${'-a'.repeat(8_000)}/a. OWASP has a good example of why this occurs, but the TL;DR is the /a at the end ensures this route would never match but due to naive backtracking it will still attempt every combination of the :a-:b on the repeated 8,000 -a.

Because JavaScript is single threaded and regex matching runs on the main thread, poor performance will block the event loop and can lead to a DoS. In local benchmarks, exploiting the unsafe regex will result in performance that is over 1000x worse than the safe regex. In a more realistic environment using Express v4 and 10 concurrent connections, this translated to average latency of ~600ms vs 1ms.
