CVE-2026-46620Public exploitNetwork attack vector

Unauthorized comment moderation via token-optional CSRF validation

Published May 26, 2026 · Updated May 26, 2026

Cross-site request forgery in e107 before 2.3.5 allows remote attackers to approve or delete comments through a moderator's browser. The comment.php approve and delete handlers execute state changes when session_handler::check() receives no CSRF token because validation runs only when a token is present. Exploitation requires a logged-in administrator or moderator to open an attacker-controlled page, after which arbitrary site comments can be silently approved or deleted.
