GHSA-C857-9X2M-CVH2 org.mariadb:r2dbc-mariadb vulnerable to cleartext password disclosure to a man-in-the-middle server (clear-text auth plugins not gated on a secure transport)

Summary The connector does not gate clear-text password authentication plugins on transport encryption. A hostile or man-in-the-middle MariaDB server can request a clear-text plugin over an unencrypted plain-TCP connection, and the driver responds with the user's password in cleartext on the wire...
