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

medium Tenable Cloud Security Plugin ID 462120

Description

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

 - A flaw was found in Keycloak, an open-source identity and access management solution. When a user account
 is temporarily locked due to repeated failed login attempts, an attacker with valid client credentials can
 exploit the Client-Initiated Backchannel Authentication (CIBA) flow to bypass this brute-force protection.
 This allows continued authentication attempts and token issuance even when the account should be locked,
 potentially enabling further unauthorized access attempts. (CVE-2026-9798)

Solution

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