Chainguard: multiple keycloak-26.8 packages: security update to 26.8.1-r4

medium Tenable Cloud Security Plugin ID 478128

Description

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

 - MariaDB Connector/J is used to connect applications developed in Java to MariaDB and MySQL databases. From
 3.0.0 until 3.3.7, 3.4.5, and 3.5.11, the connector assumed result bytes were UTF-8 but guarded only
 changes to character_set_client. It did not reject non-UTF-8 character_set_results changes and relied on
 the server's global session_track_system_variables configuration to report character-set changes. A
 malicious or compromised server, or a machine-in-the-middle attacker, could suppress tracking or change
 the result charset so application strings differed from the returned bytes, potentially defeating
 application-side validation or escaping that depended on the decoded values. This issue is fixed in
 versions 3.3.7, 3.4.5, and 3.5.11. (CVE-2026-119281)

Solution

Update the keycloak-26.8 library and its related packages to version 26.8.1-r4 or later.
