hunting-http-request-smuggling-and-desync skillA

hunting-http-request-smuggling-and-desync is agent-read markdown (skill) from unboundcompute/security-agent-skills: Hunt for request smuggling where two HTTP processors on the same path disagree about where one request ends and the next begins: a front end and back end that resolve conflicting Content-Length and Transfer-Encoding headers differently, a proxy that forwards a body the origin re-parses, a keep-alive connection where a smuggled prefix poisons the next user's request, and a rewrite or normalization difference that desyncs the stream. Covers chained HTTP/1.1 processors, proxies, load balancers, and.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
