GHSA-42R5-VHPQ-M858 MariaDB has Cleartext Transmission of Sensitive Information and Insufficiently Protected Credentials

Summary When PAM dialog authentication is used, the connector can be coerced into sending the account password in cleartext over an insecure connection. A hostile or man-in-the-middle server can trigger this with the default configuration, disclosing the user's password. Details The...

Insufficiently Protected Credentials

Overview Affected versions of this package are vulnerable to Insufficiently Protected Credentials via the SendPamAuthPacketFactory function. An attacker can intercept sensitive credentials by performing a man-in-the-middle attack or controlling a malicious server that issues an Authentication...

CVE-2026-55215

MariaDB Connector/Node.js is used to connect applications developed on Node.js to MariaDB and MySQL databases. Prior to versions 3.3.3, 3.4.6, and 3.5.3, when ssl is enabled without a pinned CA or server certificate, MariaDB Connector/Node.js sends credentials before completing certificate...

Insufficiently Protected Credentials

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...

GHSA-CQHC-2H57-WPXF MariaDB's connector leaks the cleartext password to an MitM despite `ssl: true`

Summary When SSL/TLS is enabled but no CA / server certificate is provided, the connector verifies the server's identity using fingerprint validation. The check is effective, the connection is ultimately rejected when it fails, but it happens after the authentication exchange. As a result, the...
