Notes

rodrigo-zaiden

priority bumped to high as it was listed in CISA KEV. was previously a low.

yomonokio

pcs vendors jQuery 1.9.1 on xenial/bionic/focal (in range >=1.0.3 <3.5.0) and 3.6.0 on jammy+ (fixed); noble+ ships no jQuery at all. The CVE's mechanism requires the app to sanitize HTML before passing it to .html()/.append() and jQuery to then undo that sanitization; pcsd never sanitizes before these calls, so the specific bypass path is not exercised. Marking not-affected. Caveat: pcsd's own unescaped .html()/.append() calls with server/user-supplied strings are a possible independent first-party XSS concern, out of scope here.
