Echo: keycloak-25: security update to 25.0.6+e1

high Tenable Self-Hosted Container Security Plugin ID 459211

Description

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

 - A flaw was found in Keycloak. Keycloak's Security Assertion Markup Language (SAML) broker endpoint does
 not properly validate encrypted assertions when the overall SAML response is not signed. An attacker with
 a valid signed SAML assertion can exploit this by crafting a malicious SAML response. This allows the
 attacker to inject an encrypted assertion for an arbitrary principal, leading to unauthorized access and
 potential information disclosure. (CVE-2026-2092)

Solution

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