Original Description

A flaw was found in the Keycloak identity and access management system when Fine-Grained Admin Permissions (FGAPv2) are enabled. An administrative user with the manage-users role can escalate their privileges to realm-admin due to improper privilege enforcement. This vulnerability allows unauthorized elevation of access rights, compromising the intended separation of administrative duties and posing a security risk to the realm.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
