Stored XSS via unsanitized post titles
Published Dec 18, 2025 · Updated Dec 18, 2025
Stored XSS in Tuzitio Camaleon CMS 2.7.4 allows remote authenticated users to run JavaScript through a crafted post title. The post-creation flow stores an SVG onmouseover handler in the title without neutralizing it before the title is rendered. Administrator access is required to create the post, and another user's pointer interaction executes the script in that user's session.
