CVE-2025-13622Network attack vector

Reflected XSS via unescaped admin.php PATH_INFO

Published Dec 5, 2025 · Updated Apr 8, 2026

Reflected XSS in Missi Jabbernotification 0.99-RC2 and earlier allows remote attackers to inject scripts through admin.php PATH_INFO. The plugin places attacker-controlled PATH_INFO from an admin.php request into page output without sufficient sanitization or context-appropriate escaping. No authentication is required, but execution depends on a user following a crafted link; the script then runs in that user's WordPress origin.
