Published Dec 14, 2023 · Updated Apr 28, 2026

Stored XSS in Andreas Münch Multiple Post Passwords 1.1.1 and earlier allows remote authenticated users to run script in a privileged user's browser. The settings screen renders stored plugin option values without context-appropriate output escaping. Administrator privileges are required to store the payload, and execution requires a privileged user to open the affected settings screen; the script is limited to that browser session.
