Versions of the package mysql2 before 3.9.4 are vulnerable to Prototype Poisoning due to insecure results object creation and improper user input sanitization passed through parserFn in text_parser.js and binary_parser.js.
Weakness
The product receives input from an upstream component that specifies attributes that are to be initialized or updated in an object, but it does not properly control modifications of attributes of the object prototype.
