Authenticated script execution via unsanitized SVG uploads
Published Jul 27, 2024 · Updated Apr 8, 2026
Stored XSS in aThemes Starter Sites 1.0.53 and earlier allows remote authenticated users to inject scripts through SVG uploads. The plugin accepts SVG files without adequately sanitizing embedded active content or safely escaping that content when the file is served. Author-level access or higher is required, and the injected code executes in the browser of a person who accesses the uploaded SVG.
