Description
MariaDB Connector/Node.js is used to connect applications developed on Node.js to MariaDB and MySQL databases. Prior to 3.2.5, 3.3.4, 3.4.7, and 3.5.4, text-protocol escaping always prefixes quotes with a backslash and does not honor the session's NO_BACKSLASH_ESCAPES mode, including in Connection.escape(). When that mode is enabled, the backslash is an ordinary character, so an attacker-controlled placeholder value can close the SQL string literal and inject arbitrary SQL with the application's database privileges. The vulnerable configuration may be enabled server-wide, through connector initialization options, or with an application-issued SET sql_mode; execute() and batch() use binary protocols and are not affected. This issue is fixed in versions 3.2.5, 3.3.4, 3.4.7, and 3.5.4.
