Hunting skill for ssrf vulnerabilities. Built from 15 public bug bounty reports including AWS metadata SSRF (HackerOne $25k Analytics PDF, Shopify Exchange $25k, Capital One 106M-record breach, Dropbox/HelloSign $4,913), GCP metadata SSRF (Snapchat $4k), Azure IMDS SSRF (Azure DevOps $15k chain, ChatGPT Custom Actions MSRC), DNS rebinding SSRF (Concrete CMS, GitLab UrlBlocker), gopher-protocol-to-Redis-RCE (Yahoo Mail $15k), link-preview SSRF (Reddit Matrix $6k), and headless-browser…
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
## Crown Jewel Targets SSRF is highest-value when the target runs on cloud infrastructure (AWS, GCP, Azure) where metadata services expose credentials, or when the server sits inside a complex internal network (Kubernetes clusters, microservice meshes, internal APIs). Priority targets: - **Cloud-hosted SaaS products** (GCP metadata at `169.254.169.254` or `metadata.google.internal`, AWS IMDSv1) - **Kubernetes/orchestration platforms** — aggregated API servers, metrics-server, kubelet endpoints expose privileged cluster operations - **Internal developer tooling** — CI/CD, workflow orchestration (Flyte, Argo), admin panels not exposed externally - **Link preview / URL fetching features** — Reddit-style preview APIs, Slack-style unfurling, media processors - **Dataset/file import pipelines** — anything that fetches remote URLs on behalf of a user - **Enterprise self-hosted software** (GitHub Enterprise, GitLab) — SSRF frequently chains to RCE via internal services Payouts are highest when SSRF reaches: cloud credentials → account takeover, internal admin APIs → data exfil, or chains to RCE. --- ## OOB-Or-It-Didn't-Happen Gate (Read First) …

How to install
mdr add novaestellar/novahaku/hunt-ssrf@sha256:d322427bc81cbb25The line at the top of this page pins the label git:20260910.546fe86, 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.
