[dependabot[bot]]

Bumps rails-html-sanitizer from 1.6.0 to 1.6.1.

Release notes

Sourced from rails-html-sanitizer's releases.

1.6.1 / 2024-12-02

This is a performance and security release which addresses several possible XSS vulnerabilities.

• The dependency on Nokogiri is updated to v1.15.7 or >=1.16.8.

  This change addresses CVE-2024-53985 (https://github.com/rails/rails-html-sanitizer/security/advisories/GHSA-w8gc-x259-rc7x).

• Disallowed tags will be pruned when they appear in foreign content (i.e. SVG or MathML content), regardless of the prune: option value. Previously, disallowed tags were "stripped" unless the gem was configured with the prune: true option.

  The CVEs addressed by this change are:

  • CVE-2024-53986 (https://github.com/rails/rails-html-sanitizer/security/advisories/GHSA-638j-pmjw-jq48)
  • CVE-2024-53987 (https://github.com/rails/rails-html-sanitizer/security/advisories/GHSA-2x5m-9ch4-qgrr)

  Mike Dalessio

• The tags "noscript", "mglyph", and "malignmark" will not be allowed, even if explicitly added to the allowlist. If applications try to allow any of these tags, a warning is emitted and the tags are removed from the allow-list.

  The CVEs addressed by this change are:

  • CVE-2024-53988 (https://github.com/rails/rails-html-sanitizer/security/advisories/GHSA-cfjx-w229-hgx5)
  • CVE-2024-53989 (https://github.com/rails/rails-html-sanitizer/security/advisories/GHSA-rxv5-gxqc-xx8g)

  Please note that we may restore support for allowing "noscript" in a future release. We do not expect to ever allow "mglyph" or "malignmark", though, especially since browser support is minimal for these tags.

  Mike Dalessio

• Improve performance by eliminating needless operations on attributes that are being removed. #188
