The issue occurs when a protocol mapper is configured to emit structured claims using the JSON type. The security check designed to remove unauthorized role mappings only looks for standard Java maps and fails to recognize Jackson based JSON objects. This allows an attacker to inject forged client roles into security tokens, which could lead to unauthorized access to protected resources.","score":6.5,"severity":"medium","published":"2026-11-06T06:03:03.806Z","modified":"2026-11-09T22:46:20.840Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"Red
