QID 983438

QID 983438: Nodejs (npm) Security Update for engine.io-client (GHSA-4r4m-hjwj-43p8)

Affected versions of `engine.io-client` do not verify certificates by default, and as such may be vulnerable to Man-in-the-Middle attacks.

The vulnerability is related to the way that node.js handles the `rejectUnauthorized` setting. If the value is something that evaluates to false, such as undefined or null, certificate verification will be disabled.



## Recommendation

Update to version 1.6.9 or later.

If you are unable to upgrade, ensure all calls to socket.io to have a `rejectedUnauthorized: true` flag.

Successful exploitation of this vulnerability may affect the confidentiality, integrity, and availability of the targeted user.
