Professional / Community 2025.12.1

Summary: PortSwigger released Burp Suite Professional and Community 2025.12.1 as an Early Adopter build on Tuesday, 16 December 2025 at 09:41 UTC. The release upgrades Burp's embedded browser to Chromium 143.0.7499.110 for Windows and Mac and 143.0.7499.109 for Linux.
Key Takeaway: The bundled browser is the environment where testers render and attack target applications, so its Chromium version determines which rendering and engine-level behaviors the tooling reflects; teams pinned to older builds are testing against a different browser than the one the release now ships.
