JQuery < 3.4.0 Object Prototype Pollution Vulnerability

Medium Nessus Plugin ID 124719


The remote web server is affected by an object pollution vulnerability.


The version of JQuery library hosted on the remote web server is prior to 3.4.0. It is, therefore, affected by an object pollution vulnerability in jQuery.extend(true, {}, ...) because of Object.prototype pollution. If an unsanitized source object contained an enumerable __proto__ property, it could extend the native Object.prototype.


Upgrade to JQuery version 3.4.0 or later.
