  "details": "## Summary\n\n**Description**\n\nAn Information Exposure Through Sent Data (CWE-201) issue in OpenAM\u0027s Cross-Domain Single Sign-On (CDSSO) servlet allows a logged-in user\u0027s raw OpenAM session token to be POSTed to an attacker-controlled URL. 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\u0027s 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 \u2014 an authenticated user must be induced to visit an attacker-crafted URL \u2014 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.",
