CVE-2026-43934 Details
Description
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.
A broken access control vulnerability has been identified in e107 content management system versions prior to 2.3.4. This vulnerability allows an unauthorized authenticated user to edit comments made by others. The issue arises from insufficient server-side access control validation, as the application relies solely on a predictable identifier in the request to determine which comment to edit, without verifying the requesting user's ownership of the comment. Exploitation of this vulnerability could lead to unauthorized modifications of comment content, creating opportunities for spreading misinformation or harassing users by altering their comments.
Users can update to e107 version 2.3.4, where this vulnerability has been fixed. Alternatively, comment editing can be disabled by setting the 'allowCommentEdit' preference to off in the admin Preferences.
