CVE-2026-49224: CWE-639: Authorization Bypass Through User-Controlled Key in givanz Vvveb
Vvveb CMS versions prior to 1.0.8.4 contain an authorization bypass vulnerability in the backend post revision operations. Low-privileged Authors can access, restore, or delete post revisions belonging to other Authors due to improper validation of user-controlled parameters without enforcing the current admin_id. This can lead to exposure of draft content, unauthorized content modification, and loss of audit history. The issue is fixed in version 1.0.8.4.
AI Analysis
Technical Summary
CVE-2026-49224 is an authorization bypass vulnerability in Vvveb CMS before version 1.0.8.4. The backend controller admin/controller/content/revisions.php and associated SQLite queries do not consistently enforce ownership checks by the current admin_id when handling post revisions. This allows a low-privileged Author to manipulate post_id, language_id, and created_at parameters to read, restore, or delete revisions of posts owned by other Authors. The flaw enables unauthorized disclosure of historic post content, unauthorized overwriting of live post content, and deletion of revision records, compromising content integrity and audit trails. The vulnerability is addressed in Vvveb version 1.0.8.4.
Potential Impact
An attacker with low-privileged Author access can bypass authorization controls to read confidential draft content of other users, overwrite published content by restoring unauthorized revisions, and delete revision history records. This results in confidentiality breaches, integrity violations of published content, and loss of auditability within the CMS.
Mitigation Recommendations
Upgrade Vvveb to version 1.0.8.4 or later, where this authorization bypass vulnerability is fixed. No additional mitigation is required once the update is applied.
