CVE-2024-22414Public exploitNetwork attack vector

Stored XSS via unescaped profile comments

Published Jan 17, 2024 · Updated Jun 17, 2025

Stored XSS in Dogukan Urker FlaskBlog allows remote authenticated users to execute JavaScript through comments on user profile pages. The user.html template applies Jinja's safe filter to stored comment content, causing attacker-controlled markup to be rendered without escaping. A logged-in account can store the payload, but execution requires another user to visit the commenter's profile, exposing that visitor's browser context to script-controlled data access and actions.
