CVE-2026-96547 | BDVDB-2026-401031 Detail

Description#

A flaw was found in the Dynamic Client Registration component of Keycloak, an open-source identity and access management solution. The issue occurs because the system does not properly restrict which claim names can be used when setting up new clients. An attacker with valid registration credentials could create a client that incorrectly maps standard user profile information to sensitive security roles, potentially allowing them to gain unauthorized privileges on external applications that trust Keycloak tokens.
