What is CVE-2026-1180?
CVE-2026-1180 is a medium-severity server-side request forgery vulnerability in Red Hat Build of Keycloak, published on 20 Jan 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official 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.
Weakness: CWE-918
