CVE-2026-72833Public exploitNetwork attack vector

Super-admin escalation via API-key scope bypass

Published Aug 14, 2026 · Updated Aug 14, 2026

Privilege escalation in the Grav API plugin 1.0.6 through 1.0.11 allows remote authenticated users to gain super-admin access. Four privileged write controllers return early on isSuperAdmin() and never call requirePermission(), leaving a scoped key's declared cap unenforced. A leaked or delegated read-only key minted on a super-admin account can rewrite group ACL maps and grant super-admin privileges to arbitrary accounts.
