CVE-2026-11577 (GCVE-0-2026-11577)

Vulnerability from cvelistv5 – Published: 2026-06-08 11:44 – Updated: 2026-07-03 09:01

The reported behavior does not constitute a privilege escalation. Exploitation requires the attacker to already possess the manage-realm administrative role within the realm-management client. By design, the manage-realm role is intended to be equivalent in administrative authority to realm-admin. A user with manage-realm already has full administrative control over the realm. Therefore, importing users with realm-admin role mappings through POST /admin/realms/{realm}/partialImport does not grant any additional privileges beyond those already held by the administrator and does not represent a security vulnerability.

FKIE_CVE-2026-11577

Vulnerability from fkie_nvd - Published: 2026-06-08 13:16 - Updated: 2026-07-03 10:16

Severity

Summary

Rejected reason: The reported behavior does not constitute a privilege escalation. Exploitation requires the attacker to already possess the manage-realm administrative role within the realm-management client. By design, the manage-realm role is intended to be equivalent in administrative authority to realm-admin. A user with manage-realm already has full administrative control over the realm. Therefore, importing users with realm-admin role mappings through POST /admin/realms/{realm}/partialImport does not grant any additional privileges beyond those already held by the administrator and does not represent a security vulnerability.

GHSA-P5Q4-94MG-325P

Vulnerability from github – Published: 2026-06-08 15:32 – Updated: 2026-06-30 03:36

Details

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.

Severity

7.2 (High)
