GHSA-G5XC-5W98-JFVM MariaDB has possible SQL injection in Buffer parameter escaping under big5/gbk/sjis/cp932/gb18030 client charsets

Summary A SQL injection is possible when the connector escapes Buffer parameters client-side under a multi-byte client character set whose trail-byte range overlaps the ASCII backslash 0x5C: big5, gbk, sjis, cp932, and gb18030. Under these charsets, an attacker-controlled lead byte can absorb the...

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...
