• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.1% probability of exploitation in the next 30 days
• Public exploit or detection template: none known

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.
