Stored XSS via nonce-less admin option updates
Published Aug 28, 2025 · Updated Apr 28, 2026
CSRF in Aaron Axelsen WPMU Ldap Authentication 5.0.1 and earlier allows remote attackers to store script in WordPress admin pages. Affected admin option handlers accept requests without nonce validation and persist or render values without adequate sanitization or output escaping. Exploitation requires an authenticated Network Administrator to visit attacker-controlled content; the stored script then executes when a vulnerable admin page is viewed.
