CVE-2025-30811Network attack vector

Unauthorized actions via missing nonce validation

Published Mar 27, 2025 · Updated Apr 28, 2026

Cross-site request forgery in Javier Revilla ValidateCertify Free 1.6.1 and earlier allows remote attackers to trigger unauthorized actions. A request-handling function accepts state-changing requests without valid nonce verification; public records do not identify the function or action. Exploitation requires a logged-in administrator to visit a crafted page or click a malicious link, and the consequence is limited to actions permitted by that session.
