This high-severity CVE scores 8.3 under the CNA's CVSS (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

OpenAM Unauthenticated Session Hijacking via Information Exposure in CDCServlet

Summary

Description

An Information Exposure Through Sent Data (CWE-201) issue in OpenAM's Cross-Domain Single Sign-On (CDSSO) servlet allows a logged-in user's 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.

An 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.

Impact

OpenAM 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.

Patch

This has been patched in OpenAM Community Edition version 16.1.1. Users are encouraged to update to the latest release.
