Summary
Webrecorder packages are vulnerable to XSS through 404 error handling logic
Details

A Reflected Cross-Site Scripting (XSS) vulnerability exists in the 404 error handling logic of wabac.js v2.23.10 and below. The parameter requestURL (derived from the original request target) is directly embedded into an inline <script> block without sanitization or escaping.

This allows an attacker to craft a malicious URL that executes arbitrary JavaScript in the victim’s browser.

The scope may be limited by CORS policies, depending on the situation in which wabac.js is used.

Patches

The vulnerability is fixed in wabac.js v2.23.11.
