CVE-2026-72828: Improper Privilege Management in getgrav grav
Grav Plugin API (getgrav/grav-plugin-api) before 1.0.13 fails to enforce API-key scope caps in InvitationsController. The strip-super and accept-groups decisions are gated on a bare isSuperAdmin() check rather than a scope-aware permission check, so a least-privilege API key (scoped to api.users.write) minted on a super account can create an invitation record containing super-admin access flags. When the invitation is accepted, those flags are written verbatim to the new account, resulting in privilege escalation to a fully controlled super account.
AI Analysis
Technical Summary
The Grav Plugin API (getgrav/grav-plugin-api) before version 1.0.13 contains an improper privilege management vulnerability in the InvitationsController. The code gates the strip-super and accept-groups decisions using a bare isSuperAdmin() check rather than verifying API key scopes. Consequently, an API key with limited scope (api.users.write) but issued by a super admin can create invitation records embedding super-admin flags. Acceptance of these invitations leads to the creation of accounts with unintended super admin privileges, effectively escalating privileges beyond the intended scope.
Potential Impact
An attacker with a scoped API key (api.users.write) minted on a super admin account can escalate privileges by creating invitations that grant super admin access. This results in the creation of fully controlled super admin accounts upon acceptance of the invitation, compromising the integrity and security of the Grav system.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, avoid using API keys minted on super admin accounts with limited scopes for invitation creation or restrict invitation acceptance processes to trusted users only.
