Root Cause Analysis

The vulnerability stems from LOAD DATA LOCAL INFILE being enabled by default. The commit patching this adds a 'localInfile' option and modifies ConnectionConfig.getDefaultFlags to conditionally disable LOCAL_FILES. In the vulnerable version (2.17.1):

Query.prototype['LocalInfileRequestPacket'] in Query.js executed _sendLocalDataFile without checking if the feature was explicitly allowed, relying solely on the default-enabled CLIENT_LOCAL_FILES flag.
ConnectionConfig.getDefaultFlags in ConnectionConfig.js always included LOCAL_FILES (no '-LOCAL_FILES' push when localInfile=false), leaving the client vulnerable to file exfiltration.
