This impacts OpenAM Community Edition through version 16.0.6. This issue was patched in version 16.1.1.\n\nAn attacker who can induce a logged-in victim to visit a crafted URL may receive the victim's session credential, which could enable session hijacking.\n\n## Impact\nOpenAM deployments through version 16.0.6 that have CDSSO enabled are potentially affected. The CDSSO component is commonly enabled in multi-domain deployments. Exploitation requires user interaction — an authenticated user must be induced to visit an attacker-crafted URL — and is further gated on a non-default configuration being absent.\n\n## Patch\nThis has been patched in OpenAM Community Edition version 16.1.1. Users are encouraged to update to the latest release.\n\n## Affected packages\n\n- `org.openidentityplatform.openam:openam-federation <= 16.0.6`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `org.openidentityplatform.openam:openam-federation 16.1.1`","depth":"twilight","depthScore":46,"depthScoreParts":{"impact":45.7,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
