Lifecycle Timeline

A flaw was found in Keycloak. A limited administrator can exploit an improper access control vulnerability in the POST /admin/realms/{realm}/partialImport endpoint. This allows them to bypass Fine-Grained Admin Permissions (FGAP) and escalate their privileges to a full realm administrator by importing users with realm-admin role mappings.
AnalysisAI
Privilege escalation in Keycloak allows a limited administrator to become a full realm administrator by importing users with realm-admin role mappings via the POST /admin/realms/{realm}/partialImport endpoint, bypassing Fine-Grained Admin Permissions (FGAP). Exploitation requires a high-privilege authenticated user, and while a proof-of-concept exploit exists, the EPSS score is very low (0.03%) and there is no evidence of active exploitation.
