Log-entry modification via missing AJAX nonce
Published Mar 15, 2024 · Updated Apr 28, 2026
CSRF in Cozmoslabs Paid Member Subscriptions 2.10.4 and earlier allows remote attackers to modify log entries through a forged request. The ajax_add_log_entry AJAX handler processes state-changing input without valid nonce verification, allowing a cross-site request to run in an administrator's session. Exploitation requires an authenticated administrator to follow a malicious link or submit a crafted form; the demonstrated consequence is unauthorized log-entry modification.
