Summary

The Grav API plugin (grav-plugin-api) before 1.0.36 lets delegated user managers gain super-admin access by storing positive scalar admin or api parent grants. An attacker with api.users.write can edit account access maps or invitations so the inheriting permission resolver satisfies requireSuper checks, which opens super-only API endpoints. The weakness is classified as CWE-269, Improper Privilege Management, with a CVSS 4.0 base score of 8.6 (HIGH).
