The vulnerability of the built-in reverse proxy server in the Go programming language is related to insufficient checking of requests on the server side. Exploiting this vulnerability allows a remote attacker to perform an SSRF attack...

Improper Authentication

Kirby is vulnerable to Improper Authentication. The vulnerability is due to incorrect trust of the Forwarded, X-Client-IP, and X-Real-IP request headers during local IP validation, which allows a remote attacker to bypass the installation restriction and create the first administrator account on...

http4k: `reverseProxy()` defaulted to substring (`Contains`) matching on `Host`; tightened to `Exact`

Impact reverseProxy and reverseProxyRouting matched configured vhosts by substring on the Host header Contains matcher by default. The intended use of these functions in http4k is outbound dispatch e.g. matching AWS service subdomains, per the Contains docstring and test-time composition of fake...

SwiftNIO HTTP/2: HTTP/2-to-HTTP/1 Request Smuggling via unvalidated :path pseudo-header in HTTP2ToHTTP1Codec

swift-nio-http2's HTTP/2-to-HTTP/1.1 codec HTTP2FramePayloadToHTTP1ServerCodec / HTTP2ToHTTP1ServerCodec did not validate pseudo-header values for control characters before placing them into the translated HTTP/1.1 message. A remote attacker could send an HTTP/2 request containing CR \r, LF \n, o...

Arc: Unauthenticated access to Go debug pprof endpoints leaks runtime state and enables CPU-burn DoS

Summary Arc registers Go's net/http/pprof handlers at /debug/pprof/ via app.Usepprof.New in internal/api/server.go, and /debug/pprof is added to PublicPrefixes in cmd/arc/main.go. The auth middleware short-circuits before the token check on prefix match, so the endpoints are reachable without any...

Use of GET Request Method With Sensitive Query Strings
