Stored XSS via forged unsanitized settings update
Published Jun 27, 2022 · Updated Aug 3, 2024
Stored cross-site scripting in Add Post URL 2.1.0 and earlier allows remote attackers to inject script through a forged settings request. The settings handler accepts a crafted footer_text value without a CSRF token, sanitization, or output escaping and renders it in posts. Exploitation requires an administrator with an active WordPress session to visit an attacker-controlled page; the submitted script then executes for visitors to affected posts.
