CVE-2026-45049 is a high-severity security vulnerability in org.openidentityplatform.openam:openam-federation (maven), affecting versions <= 16.0.6. It is fixed in 16.1.1.
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.
CVE-2026-45049 has a CVSS score of 8.3 (High). The vector is network-reachable, no privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment.
A fixed version is available (16.1.1). Upgrading removes the vulnerable code path.

org.openidentityplatform.openam:openam-federation (<= 16.0.6)org.openidentityplatform.openam:openam-federation → 16.1.1 (maven)Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter instead of chasing every advisory.

CVE-2026-45049 is a high-severity security vulnerability in org.openidentityplatform.openam:openam-federation (maven), affecting versions <= 16.0.6. It is fixed in 16.1.1.
CVE-2026-45049 has a CVSS score of 8.3 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
org.openidentityplatform.openam:openam-federation (maven) versions <= 16.0.6 is affected.
Yes. CVE-2026-45049 is fixed in 16.1.1. Upgrade to this version or later.
Whether CVE-2026-45049 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
Upgrade org.openidentityplatform.openam:openam-federation to 16.1.1 or later.
