Language: JavaScript

Severity: Notice

Category: Best Practices

JavaScript URLs are evaluated the same way eval is executed. This can lead to arbitrary code execution.

var a = 'javascript:void(0);';
var a = 'javascript:';
var a = `javascript:`;
var a = `JavaScript:`;

var a = 'Hello World!';
var a = 10;
var url = 'xjavascript:'
var url = `xjavascript:`
var url = `${foo}javascript:`
var a = foo`javaScript:`;
