Echo: org.mariadb.jdbc:mariadb-java-client: security update to 2.7.14

medium Tenable Self-Hosted Container Security Plugin ID 461407

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.
 Prior to 2.7.14, 3.3.5, 3.4.3, and 3.5.9, the connector encodes and decodes protocol text and performs
 client-side escaping under the assumption that the connection character set is UTF-8. The server can
 report a mid-session change to character_set_client through OK-packet session-state tracking, including a
 change caused by SET NAMES, a stored routine or trigger, server configuration, or a hostile server. If
 character_set_client changes to a non-UTF-8 value, the driver continues to read and write UTF-8 while the
 server interprets the same bytes under another encoding, causing silent data corruption and a
 client/server charset-confusion mismatch that can defeat byte-wise quoting or escaping. The fix accepts
 only utf8, utf8mb3, or utf8mb4 after initialization; any other value causes SQLException with SQLState
 08000 and closes the connection. This issue is fixed in versions 2.7.14, 3.3.5, 3.4.3, and 3.5.9.
 (CVE-2026-55858)

Solution

Update the org.mariadb.jdbc:mariadb-java-client library and its related packages to version 2.7.14 or later.
