Background
The mysql Node.js module is a popular package used for connecting to MySQL databases from Node.js applications. It provides a convenient way to interact with MySQL databases and execute queries. However, versions of the mysql package before 2.14.0 are vulnerable to remote memory exposure.
Vulnerability Detail
The vulnerability in the mysql Node.js module occurs when a number is provided as a password. Affected versions of the package allocate and send uninitialized memory over the network, potentially exposing sensitive information. This vulnerability only affects mysql running on Node.js versions below 6.0.0, as newer versions of Node.js have added a throw to prevent this issue.
How To Fix
Latest published version: 2.18.1 as of 22 Oct 2026
npm install mysql@2.18.1Upgrading to it may include breaking changes; the version below is the minimum fixed release for this vulnerability.

Workaround
If updating the mysql package is not immediately possible, a workaround can be implemented by ensuring that the password provided is not a number. This can be achieved by converting the password to a string before passing it to the mysql module. Here is an example of a workaround code snippet:
const password = String(USERPROVIDEDINPUT);
require('mysql').createConnection({
host: 'localhost',
user: 'user',
password: password,
database: 'my_db'
}).connect();
Conclusion
The mysql Node.js module versions before 2.14.0 are vulnerable to remote memory exposure when a number is provided as a password. It is recommended to update to version 2.14.0 or later to fix this vulnerability. If immediate update is not possible, a workaround can be implemented by converting the password to a string.
