Stored XSS via unsanitized SVG uploads
Published Jul 13, 2024 · Updated Aug 1, 2024
Stored XSS in Sayedul Sayem Support SVG before 1.1.0 allows remote authenticated users to run JavaScript through uploaded SVG files. The media upload path accepts and stores SVG document contents without sanitizing embedded script, which executes when the file URL is opened. Author-level access is required to upload the file, and a visitor must open its URL; the result is browser-side code execution in the site origin.
