Exploit HTTP QUERY method (RFC 10008, June 2026) parser differentials -- WAF body inspection bypass, cache poisoning via body-ignorant caching, and request smuggling from body handling disagreements. Use when target has a CDN/cache/WAF layer and accepts or forwards unknown HTTP methods, or when testing for method-based parser differentials.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# HTTP QUERY Method Exploitation RFC 10008 (June 2026) defines QUERY -- the first new HTTP method standardized in 20+ years. It is semantically GET-with-a-body: safe, idempotent, cacheable, but the response cache key MUST include the request body and Content-Type. Most infrastructure does not implement this correctly yet. The adoption gap between spec and deployment is the attack surface. ## When to Use - Target sits behind a CDN, cache, or WAF (most do) - WAF blocks injection payloads in POST bodies but you haven't tested QUERY - Cache layer detected (Varnish, Squid, CloudFront, Fastly, Cloudflare, Akamai) - Target accepts or forwards unrecognized HTTP methods (test with `curl -X QUERY`) - You've exhausted standard `parser-differential-bypass` and `h2-waf-bypass` techniques ## QUERY vs GET vs POST | Property | GET | POST | QUERY | |---|---|---|---| | Safe / idempotent | Yes / Yes | No / No | Yes / Yes | | Body | Ignored by most infra | Required | Required | | Cacheable | Yes (URL-keyed) | No | Yes (URL + body + Content-Type keyed) | | CORS safelisted | Yes | Yes (simple) | No (triggers preflight) | …

How to install
mdr add dreadnode/capabilities/http-query-method@sha256:b37daebb2337ba44The line at the top of this page pins the label git:20260706.00661a3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
