CVE-2025-25154Network attack vector

Stored XSS via missing nonce validation

Published Feb 7, 2025 · Updated Apr 28, 2026

Cross-site request forgery in Custom Comment Notifications 1.0.8 and earlier allows remote attackers to cause stored XSS. An unnamed settings-update function omits or misapplies nonce validation, so a forged request can store attacker-supplied script. Exploitation requires an authenticated administrator to interact with the forged request, after which the script executes in a WordPress user's browser.
