Subscriber-level stored XSS via unchecked snippet actions

Published Jan 8, 2025 · Updated Apr 8, 2026

Stored XSS in WP Extended – The Ultimate WordPress Toolkit 3.0.11 and earlier allows remote authenticated users to inject scripts. Several Code Snippets import and activation handlers omit capability checks before accepting and activating subscriber-supplied content. Subscriber-level access is sufficient to modify stored site content, and later rendering can execute the injected script in another user's browser session.
