Cross-site Scripting (XSS)

diagram-js is a framework for modifying diagrams in browser.

Affected versions of this package are vulnerable to Cross-site Scripting (XSS). Pasting HTML text anywhere that allows text input in the modeler evaluates the HTML as is. It can be exploited by adding a new element on the canvas and editing the name to contain html. For example, <video src=1 onerror=alert('Running a script')>

How to fix Cross-site Scripting (XSS)?

Upgrade diagram-js to version 2.6.2, 3.3.1 or higher.

<2.6.2 >=3.0.0 <3.3.1
