- phpMyFAQ: SVG Sanitizer Entity Decoding Depth Limit Bypass Leading to Stored XSS
- Details
-
phpMyFAQ before 4.1.2 contains a stored cross-site scripting vulnerability in SvgSanitizer::decodeAllEntities() that limits recursive entity decoding to 5 iterations, allowing attackers to bypass sanitization. Authenticated users with FAQ_EDIT permission can upload malicious SVG files with deeply nested ampersand encoding around numeric HTML entities to reconstruct javascript: URLs, which execute arbitrary JavaScript when clicked by other users viewing the uploaded SVG.
