medium Tenable Self-Hosted Container Security Plugin ID 459501

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A flaw was found in Keycloak. An authenticated user with existing organization membership can exploit this
 flaw by accessing user-facing APIs, such as the account API or by requesting an OpenID Connect (OIDC)
 token with the 'organization' scope. This allows organization metadata to be disclosed in tokens, even
 after an administrator has explicitly disabled the Organizations feature, potentially leading to incorrect
 authorization decisions by resource servers. (CVE-2026-9791)

Solution

Update the keycloak-25 library and its related packages to version 25.0.6+e1 or later.
