high Tenable Self-Hosted Container Security Plugin ID 463755

Description

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

 - A flaw was found in Keycloak. A remote attacker could bypass security controls by sending a valid SAML
 response from an external Identity Provider (IdP) to the Keycloak SAML endpoint for IdP-initiated broker
 logins. This allows the attacker to complete broker logins even when the SAML Identity Provider is
 disabled, leading to unauthorized authentication. (CVE-2026-2603)
