CVE ID : CVE-2026-1180
Published : Jan. 20, 2026, 1:16 p.m. | 1 hour, 27 minutes ago
Description : A flaw was identified in Keycloak’s OpenID Connect Dynamic Client Registration feature when clients authenticate using private_key_jwt. The issue allows a client to specify an arbitrary jwks_uri, which Keycloak then retrieves without validating the destination. This enables attackers to coerce the Keycloak server into making HTTP requests to internal or restricted network resources. As a result, attackers can probe internal services and cloud metadata endpoints, creating an information disclosure and reconnaissance risk.
Severity: 5.8 | MEDIUM
