HARBringer, HAR Importer

Summary: PortSwigger's BApp Store lists HARbringer, a third-party Burp extension by author abirasecurity at version 1.0.0, last updated 18 September 2025, that imports HTTP Archive (HAR) files directly into the site map while preserving the original HTTP requests and responses. The listing states the extension maintains the exact captured traffic for analysis of previously recorded sessions, and notes that extensions are written by third-party Burp users with no warranty from PortSwigger.

Bottom line: HAR files are routinely handed around during incident reviews and vendor exchanges, and this extension loads that recorded traffic straight into Burp's site map - so the captured requests and responses, credentials and session tokens included, become working material in a tester's tool. PortSwigger explicitly disclaims any warranty on third-party extensions, which puts the review of what gets installed into Burp on your team.
