Professional / Community 2021.10.3

Summary: PortSwigger released Burp Suite Professional/Community 2021.10.3 on 2 December 2021, patching a medium-severity security issue in how Burp Suite processed HTTP/2 responses that could have introduced XSS in certain circumstances. The release also upgraded Burp's browser to Chromium 96.0.4664.45, made adjustments to prevent accidental loss of Burp project files, and included several minor bug fixes, with credit to Ademar Nowasky Junior for reporting the flaw through the bug bounty program.

What's compelling: The flaw sat in Burp's own HTTP/2 response handling, so the tool security teams use to find XSS could itself have been a vector for it until users applied the patch.
