Host Header Inchecktion
Summary: PortSwigger's BApp Store lists a Burp extension called Host Header Inchecktion, version 1.3.0, by Fabian Binna, last updated 23 April 2026, which actively tests a set of injection types to find host header injection vulnerabilities and creates a scan issue when an injection succeeds. It runs during an active scan or on a manually selected request, and PortSwigger states the extension is written by a third party and carries no warranty of quality or usefulness.
Key Takeaway: Host header injection is the kind of flaw that surfaces in password-reset links and routing decisions, and this tool only flags it when an injection actually succeeds - so a clean scan depends on the injection types the extension covers, not on the absence of the bug.
