CVE-2026-109317: Grav grav-plugin-api privilege escalation in access grant validation

CVE-2026-109317 · Severity: high · CVSS 7.2 · Published 2026-10-12

Grav's API plugin improperly validates user access permissions, allowing delegated user managers to escalate their privileges to super-admin level. An attacker with api.users.write permission can manipulate account access maps or invitations to bypass super-admin permission checks, gaining unauthorized access to sensitive API endpoints that should be restricted to administrators only.

Technical details

The vulnerability exists in Grav grav-plugin-api versions before 1.0.36, where the permission validation logic fails to properly restrict scalar parent grants during access map updates. While accessGrantsSuper() blocks explicit admin.super and api.super keys, it does not reject positive scalar parent grants that can later be inherited by PermissionResolver::resolve() to satisfy requireSuper() checks. An authenticated attacker with api.users.write permission can exploit this by editing account access maps or invitations to store scalar parent grants, then use those inherited permissions to access super-only API endpoints.
