CVE-2026-88959
HighCVSS 8.8Summary
Anchor CMS through 0.12.7 fails to enforce role-based access control in admin user-management endpoints. Any authenticated low-privilege user can POST directly to admin/users/add or admin/users/edit to create administrator accounts or change the existing administrator's password.
Risk Assessment
An attacker with editor or user roles can gain full administrative access, leading to complete site compromise.
Recommendation
Restrict access to the admin/users/add and admin/users/edit endpoints and apply the fix once available. Until then, consider limiting editor and user roles.
