hunt-ssrf

hunt-ssrf is a skill for Claude Code, Codex from adriannoes/awesome-agentic-ai. It costs 31 tokens per session (4,459 once invoked), scanned C, original, MIT.

A security-testing guide for finding server-side request forgery (SSRF), a flaw where a server is tricked into making requests to unintended locations.

In plain words
What is it for?
Use it during authorized testing of link previews, imports, media processors, cloud applications, and internal developer tools.
Why use it?
It helps reveal when URL-fetching features can reach cloud credential services, private networks, or internal APIs.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

hunt-ssrf scanned grade C with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 383 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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)

Claims of blind SSRF require an out-of-band (OOB) confirmation. Always. No exceptions.

OOB means: a Burp Collaborator domain, an interactsh-client listener, a canarytoken, or any DNS+HTTP receiver you control that confirms the server actually made an outbound network connection on your behalf.

What is NOT confirmation of SSRF

  • The server echoing your URL back in an error message. Example: "The Web application at http://evil.example.com/x could not be found" — this is the server formatting your input into an error string, NOT making an outbound HTTP request. The error came from string formatting, not from network failure.
  • The server returning a different status code for an external URL vs localhost. Different error responses can come from URL-scheme validators, not from actual fetching.
  • A delayed response when the URL is sent. Delay can come from DNS resolution attempts within the parser, not from completed HTTP fetches.

hunt-ssrf is a skill published in the GitHub repository adriannoes/awesome-agentic-ai (57 stars, last pushed 14d ago), licensed MIT. It adds 31 tokens to every session and 4,459 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it C with 2 findings (cloud metadata endpoint, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
