CVE-2023-51489Network attack vector

Rating modification via missing update_rating nonce validation

Published Mar 16, 2024 · Updated Apr 28, 2026

CSRF in Automattic Crowdsignal Dashboard 3.0.11 and earlier allows remote attackers to update ratings through a forged request. The update_rating function accepts rating changes without correctly validating a WordPress nonce tied to the request. A site administrator must interact with attacker-controlled content while authenticated; the forged request alters ratings but does not disclose data.
