LOW3.8EPSS 0.03%Keycloak: Missing Check on Disabled Client for Docker Registry Protocol
發布日:2026/2/19修改日:2026/3/6
描述
A flaw was identified in the Docker v2 authentication endpoint of Keycloak, where tokens continue to be issued even after a Docker registry client has been administratively disabled. This means that turning the client “Enabled” setting to OFF does not fully prevent access. As a result, previously valid credentials can still be used to obtain authentication tokens. This weakens administrative controls and could allow unintended access to container registry resources.
