e107: CSRF in comment.php moderation endpoints via token-optional validation in session_handler::check()

Published: May 26, 2026Updated: May 26, 2026 Sources: CVE List
NVD MITRE
6.5CVSS
MEDIUM

e107 is a content management system (CMS). Prior to 2.3.5, e107 CMS does not properly enforce CSRF token validation on comment moderation actions. The problem comes down to how session_handler::check() handles CSRF tokens. Instead of requiring a token on every state-changing request, it only validates the token if one happens to be present. If there is no token at all, the check is skipped entirely. This vulnerability is fixed in 2.3.5.
