Potential XSS vulnerability. #5462

Open RahulKhandelwal17 opened 7 months ago

RahulKhandelwal17 commented 7 months ago

We are doing R&D on form.io JS library, while doing research we found a potential XSS vulnerability. The issue arises when specific text is entered during the addition of a component. To replicate, drag and drop a component and paste the following code into the Tooltip text area:

<img src=x onerror=window.open('https://www.google.com/');>

Immediately after pasting, it triggers a new tab to open. Additionally, once saved or if any further modification is made to the form, it causes redirections with each action.
