Summary: PortSwigger released Burp Suite Professional and Community 2023.10.2.3 on Friday, 20 October 2023, upgrading the built-in browser to 118.0.5993.88 for Mac and Linux and 118.0.5993.88/.89 for Windows. The release notes state the update contains a security fix and point to the Chromium release notes for details.
Bottom line: The fix is in the Chromium browser embedded in Burp, so testers running older versions carry an unpatched browser into every engagement until they update.
