What is CVE-2026-35182?

Brave CMS, an open-source content management system, contains a vulnerability that permits any authenticated user to escalate their privileges improperly. This occurs due to a missing authorization check in the update role endpoint, specifically the POST route for /rights/update-role/{id}, which lacks the necessary middleware to validate user permissions. The flaw enables users to change account roles, promoting themselves to Super Admin without proper authorization. Users are advised to upgrade to version 2.0.6, where this security issue has been addressed.
