AI Analysis
Technical Summary
BraveCMS, an open-source content management system, had a missing authorization check in its update role endpoint (routes/web.php) before version 2.0.6. Specifically, the POST route /rights/update-role/{id} lacked the middleware enforcing user permission checks for assigning roles. This allowed any authenticated user to modify account roles, including promoting themselves to Super Admin. The vulnerability is identified as CWE-862 (Missing Authorization). It has a CVSS 3.1 base score of 8.8, indicating high impact on confidentiality, integrity, and availability. The issue was resolved in version 2.0.6 of BraveCMS.
Potential Impact
An authenticated user can exploit this vulnerability to escalate their privileges to Super Admin, gaining full control over the CMS. This can lead to complete compromise of the system, including unauthorized data access, modification, and potential service disruption. The CVSS score of 8.8 reflects high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
Upgrade BraveCMS to version 2.0.6 or later, where this authorization check vulnerability has been fixed. Since the vendor advisory confirms the fix in 2.0.6, applying this official update is the recommended remediation. No other mitigations are specified or required once the patch is applied.
