e107 is a content management system (CMS). Prior to 2.3.4, a Broken Access Control vulnerability exists in the application, allowing an unauthorized authenticated user to edit comments posted by others. This stems from inadequate server-side access control validation, where the application depends only on a predictable identifier in the request to determine which comment to edit, without confirming the requesting user’s ownership of the comment. This vulnerability is fixed in 2.3.4.

No affected version ranges are stored yet. Use the vendor advisory before you decide this record does not apply.
