Professional / Community 2025.9.1

Summary: PortSwigger released Burp Suite Professional / Community 2025.9.1 on Friday, 12 September 2025 at 13:58 UTC, fixing a startup bug and upgrading Burp's browser to address a critical CVE. The release fixes a bug where Burp failed to start correctly if the Bambda library contained a Bambda with a special character in its name, adds a confirmation dialog when the escape key is pressed in the custom scan check editor, and upgrades Burp's browser to Chromium 140.0.7339.133 on Mac, 140.0.7339.128 on Windows and 140.0.7339.127 on Linux.
Why it matters: The bundled browser upgrade resolves a critical CVE, so teams running Burp for testing carry that exposure until they update - and a Bambda with a special character in its name could stop Burp from starting at all.
