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

medium Tenable Self-Hosted Container Security Plugin ID 461212

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, when a Java application connects with sslMode=verify-full or
 sslMode=verify-ca, supplies a password, and does not configure serverSslCert or trustStore, Connector/J
 can accept an untrusted self-signed certificate through the fallbackToSystemTrustStore=true ephemeral
 trust manager and record its certFingerprint for later identity binding. The OK-packet and authentication-
 switch paths enforce the certificate fingerprint, but the initial-handshake path does not.
 HandshakeResponse.encode() can therefore build and send a mysql_clear_password response before checking
 certFingerprint != null && !isMitMProof(), sslMode, or whether the authentication plugin is resistant to a
 man-in-the-middle, and the initial path also bypasses restrictedAuth. An active man-in-the-middle or
 hostile server can present a self-signed certificate, claim to be MariaDB, select mysql_clear_password as
 the initial authentication plugin, and receive the full database password before the connection is
 rejected. This issue is fixed in versions 2.7.14, 3.3.5, 3.4.3, and 3.5.9. (CVE-2026-55856)

Solution

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