Background
mxGraph is an npm package that provides a JavaScript library for creating interactive diagrams and graphs. It is widely used in web applications to visualize complex data and workflows. The package offers various features, including the ability to set tooltips for elements in the graph. However, version 4.2.2 of mxGraph has been found to contain a cross-site scripting (XSS) vulnerability in the setTooltips() function.
Vulnerability Detail
The cross-site scripting vulnerability in mxGraph's setTooltips() function allows an attacker to inject malicious code into the tooltips of graph elements. When a user hovers over an element with a manipulated tooltip, the injected code gets executed in the context of the user's browser, potentially leading to unauthorized actions, data theft, or further exploitation. This vulnerability has a CVSS score of 6.1, indicating a moderate severity level.
How To Fix

Workaround
As a temporary workaround, developers can manually sanitize the tooltip content to prevent the execution of any injected scripts. This can be done by using a library or function that escapes or removes any potentially malicious HTML or JavaScript tags from the tooltip text. Here's an example of how to sanitize the tooltip content using the DOMPurify library:
const DOMPurify = require('dompurify');
const sanitizedTooltip = DOMPurify.sanitize(tooltipContent);
Conclusion
In conclusion, mxGraph version 4.2.2 is vulnerable to a cross-site scripting (XSS) attack through the setTooltips() function. Developers should upgrade to a non-affected version of mxGraph and sanitize tooltip content to mitigate the risk of exploitation.
