CVE-2016-10536
The vulnerability is related to the way that node.js handles the `rejectUnauthorized` setting.
Does this matter?
Lower severity and a low EPSS score (1.01%). Track it; it rarely justifies an emergency change on its own.
Description
engine.io-client is the client for engine.io, the implementation of a transport-based cross-browser/cross-device bi-directional communication layer for Socket.IO. The vulnerability is related to the way that node.js handles the `rejectUnauthorized` setting. If the value is something that evaluates to false, certificate verification will be disabled. This is problematic as engine.io-client 1.6.8 and earlier passes in an object for settings that includes the rejectUnauthorized property, whether it has been set or not. If the value has not been explicitly changed, it will be passed in as `null`, resulting in certificate verification being turned off.
