NewCVE-2026-55215 (opens in a new tab)How to fix?
Upgrade mariadb to version 3.5.3 or higher.
Overview
Affected versions of this package are vulnerable to Insufficiently Protected Credentials in the authentication. An attacker can intercept sensitive credentials by performing a man-in-the-middle attack during the initial handshake.
Note: This is only exploitable if SSL/TLS is enabled without providing a CA or server certificate and the connection relies solely on fingerprint validation.
Workaround
This vulnerability can be mitigated by explicitly configuring certificate verification, providing the server/CA certificate, and using a verifying SSL mode such as VERIFY_CA or VERIFY_FULL.
