Bumps dompurify and @types/dompurify. These dependencies needed to be updated together.
Updates dompurify from 3.2.4 to 3.4.5

Release notes

Sourced from dompurify's releases.

DOMPurify 3.4.5

  • Fixed a bypass caused by the new HTML element selectedcontent added in 3.4.4, thanks @​KabirAcharya

Note that this is a security release for an issue introduced in 3.4.4 and should be upgraded to immediately.

DOMPurify 3.4.4

  • Added the selectedcontent element to default allow-list, thanks @​lukewarlow
  • Added the command and commandfor attributes to default allowed-list, thanks @​lukewarlow
  • Added better template scrubbing for IN_PLACE operations, thanks @​DEMON1A
  • Added stronger checks for cross-realm windows, thanks @​DEMON1A & @​fg0x0
  • Updated demo website and made sure it uses the latest from main
  • Updated existing workflows, fuzzer, dependabot, etc., added more tests
  • Bumped several dependencies where possible

🚨 This release had been flagged as deprecated, please use DOMPurify 3.4.5 instead 🚨

DOMPurify 3.4.3

  • Fixed an issue with handling of nested Shadow DOM trees, thanks @​fishjojo1
  • Fixed the template regexes to be more robust against ReDoS attacks, thanks @​aleung27
  • Updated the node iteration code to catch more Shadow DOM related issues
  • Updated Playwright and added Node 26 to test matrix
  • Updated existing workflows, fuzzer, release signing, etc., added more tests
  • Bumped several dependencies where possible

DOMPurify 3.4.2

  • Fixed an issue with URI validation on attributes allowed via ADD_ATTR callback, thanks @​nelstrom
  • Fixed an issue with source maps referring to non-existing files, thanks @​cmdcolin
  • Updated existing workflows, fuzzer, release signing, etc., added more tests
  • Bumped several dependencies where possible

DOMPurify 3.4.1

  • Fixed an issue with on-handler stripping for HTML-spec-reserved custom element names (font-face, color-profile, missing-glyph, font-face-src, font-face-uri, font-face-format, font-face-name) under permissive CUSTOM_ELEMENT_HANDLING
  • Fixed a case-sensitivity gap in the annotation-xml check that allowed mixed-case variants to bypass the basic-custom-element exclusion in XHTML mode
  • Fixed SANITIZE_NAMED_PROPS repeatedly prefixing already-prefixed id and name values on subsequent sanitization
  • Fixed the IN_PLACE root-node check to explicitly guard against non-string nodeName (DOM-clobbering robustness)
  • Removed a duplicate slot entry from the default HTML attribute allow-list
  • Strengthened the fast-check fuzz harness with explicit XSS invariants, an expanded seed-payload corpus, an additional idempotence property for SANITIZE_NAMED_PROPS, and a negative-control assertion ensuring the invariants actually fire
  • Added regression and pinning tests covering the above fixes and two accepted-behavior contracts (SAFE_FOR_TEMPLATES greedy scrub, hook-added attribute handling)
  • Extended CodeQL analysis to run on 3.x and 2.x maintenance branches

DOMPurify 3.4.0

Most relevant changes:

  • Fixed a problem with FORBID_TAGS not winning over ADD_TAGS, thanks @​kodareef5
  • Fixed several minor problems and typos regarding MathML attributes, thanks @​DavidOliver
  • Fixed ADD_ATTR/ADD_TAGS function leaking into subsequent array-based calls, thanks @​1Jesper1
  • Fixed a missing SAFE_FOR_TEMPLATES scrub in RETURN_DOM path, thanks @​bencalif
  • Fixed a prototype pollution via CUSTOM_ELEMENT_HANDLING, thanks @​trace37labs
  • Fixed an issue with ADD_TAGS function form bypassing FORBID_TAGS, thanks @​eddieran
  • Fixed an issue with ADD_ATTR predicates skipping URI validation, thanks @​christos-eth
