Bumps dompurify from 3.3.3 to 3.4.5.

Release notes

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
