CVE-2026-46620 Details
Description
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.
A cross-site request forgery (CSRF) vulnerability has been identified in e107 CMS versions prior to 2.3.5. The issue arises because the CMS does not consistently enforce CSRF token validation for comment moderation actions. The vulnerability allows an attacker to create a webpage that can silently delete or approve comments on behalf of a logged-in admin or moderator, without their knowledge. This exploitation takes advantage of the 'session_handler::check()' function, which only validates tokens if they are present, effectively skipping the check for requests without a token.
Users can upgrade to e107 version 2.3.5, where this vulnerability is fixed. After the update, ensure that AJAX calls to comment moderation endpoints include a valid CSRF token. Until the update is applied, access to 'comment.php' moderation endpoints can be restricted at the web server or firewall level, or AJAX comment moderation can be temporarily disabled from the admin panel.
