When a custom truststore is provided to verify the server identity, the tool incorrectly accepts any self-signed certificate as long as the hostname matches. This allows a network attacker to impersonate the Keycloak server, steal administrative credentials, and perform unauthorized management actions.\n\n## Affected\n\n- `keycloak-core`\n- `keycloak-admin-cli (all versions)`\n- `rhbk/keycloak-rhel9 (all versions)`\n- `rhbk/keycloak-rhel9-operator (all versions)`\n- `keycloak-core`\n- `jboss-eap-7/eap74-els-openjdk11-openshift-rhel8`\n- `jboss-eap-7/eap74-els-openjdk17-openshift-rhel8`\n- `jboss-eap-7/eap74-els-openjdk8-openshift-rhel8`\n- `keycloak-core`\n- `keycloak-core`\n- `candlepin`\n- `keycloak-admin-cli (all versions)`\n- `keycloak-core`\n- `rh-sso7-keycloak (all versions)`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n### Workarounds\n\nMitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.","depth":"twilight","depthScore":44,"depthScoreParts":{"impact":44,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
