Post status changes via missing nonce validation

Published Oct 4, 2025 · Updated Oct 4, 2025

Cross-site request forgery in Trinity Audio WordPress Plugin 5.20.2 and earlier allows remote attackers to alter post status via forged requests. The admin/inc/post-management.php handler processes activation and deactivation requests without valid WordPress nonce verification. Exploitation requires a logged-in site administrator to follow a crafted link, after which posts can be activated or deactivated without the administrator's intent.
