CVE-2026-72828
HighCVSS 7.2Exploitation Probability (EPSS)
Low risk20th percentile - higher than 20% of all known CVEs
Summary
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.
Risk Assessment
Privilege escalation can lead to full takeover of a super-admin account, enabling unauthorized access to all resources and data of the Grav system.
Recommendation
Upgrade Grav Plugin API to version 1.0.13 or later, which includes the fix, and review API keys for excessive permissions.
