Bounty URL: https://www.huntr.dev/bounties/1-npm-jquery-confirm
⚙️ Description *
The project
jquery-confirmadds classes to HTML elements without any validation causing an HTML Injection.💻 Technical Description *
The code dynamically creates an HTML element for the
setIconandcloseIconClassactions and adds classes directly to the elements making it vulnerable to an HTML Injection Vulnerability.The implementation should not be like this and sanitizing/escaping the input class is also not the way as there is a dedicated function in JQuery to do just what we want ==
addClass().This is also suggested by the reporter of this vulnerability: #508 (comment).
🐛 Proof of Concept (PoC) *
🔥 Proof of Fix (PoF) *
As suggested by the reporter, I implemented the JQuery dedicated function
addClass()to add class to the particular dynamically created element completely preventing any bypasses possible.👍 User Acceptance Testing (UAT)
Just added a JQuery function on a JQuery project. 😉
