Stored XSS via unsanitized SVG uploads
Published Nov 9, 2024 · Updated Apr 8, 2026
Stored XSS in Lenxel AI LMS – Course Lesson Generator 1.2.3 and earlier allows remote authenticated users to inject scripts via SVG uploads. The SVG upload path accepts attacker-controlled active content without sufficient sanitization and later serves it without safe output escaping. Author-level access or higher is required, and the script runs in a visitor's browser when the uploaded SVG file is opened.
