Stored XSS via unescaped 404 URL field
Published Jul 17, 2022 · Updated Aug 3, 2024
Stored cross-site scripting in WordPress 404s Plugin before 3.5.1 allows remote authenticated users to execute script in a viewer's browser. When an administrator creates or edits a 404 entry, the plugin stores the URL field without sanitizing it and later renders the value without output escaping. Administrator privileges are required, and exploitation also requires another user to view the stored entry; the resulting script runs in that user's site context.
