response-queue-poisoning skillA

response-queue-poisoning is agent-read markdown (skill) from dreadnode/capabilities: Escalate HTTP header injection (CRLF in URL path or parameters) to critical impact via response queue poisoning and request tunnelling — smuggle requests through persistent connections to capture victim responses or bypass proxy ACLs. Use when CRLF injection exists in request headers/path and front-end maintains persistent backend connections..

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.
