This link is maintained to preserve external references.\n\n### Original Description\nGrav before 2.0.14 fails to guard the access field in the core group blueprint with the required security@: admin.super restriction. A delegated admin.users operator can save a group with access[admin][super]=true to escalate to super-admin, gaining scheduler and Twig evaluation capabilities.\n\n## Affected packages\n\n- `getgrav/grav < 2.0.14`\n\n## Remediation\n\nRefer to the advisory for the patched release.","depth":"midnight","depthScore":50,"depthScoreParts":{"impact":50.1,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
