JS Vulnerability Detector

JavaSript Vulnerability Detector is a result of my Master Thesis at Brno University of Technology, Faculty of Information technology, graduation year 2022. The extension aims to add security features to the end-users of various websites containing vulnerable JavaScript library code. The principle of extension is following:

1. After page loads the extension scans all the JavaScript contained on the page and sends it to background script for processing.

2. If the script contains a known vulnerability (initial version focuses mostly on jQuery), it is tracked and shown in the extension popup. After detection the vulnerable script can be blocked, patched or left as is and only tracked.

All data is stored locally and can be cleared by a "Clear" button in the extension popup. There is no server communication going on, no data leaves the browser.

Extension runs in 4 modes:

1. disabled - no action
