CVE-2026-45049OpenAM Session Hijacking via CDSSO

Updated under an hour ago ()

Does this affect you?

It affects OpenIdentityPlatform OpenAM. Add what you run to find out whether that includes you.

No exploitation reported and no EPSS estimate yet.

Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, the `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. An attacker who induces an authenticated victim to visit a crafted URL can receive the session credential and potentially hijack the session. Deployments must have `CDSSO` enabled, as is common in multi-domain deployments, and exploitation is additionally gated on a non-default configuration being absent. This issue is fixed in version 16.1.1.
