ssrf-methodology

ssrf-methodology is a skill for Claude Code, Codex from wgpsec/AboutSecurity. It costs 113 tokens per session (1,183 once invoked), scanned C, original, no licence file.

A guide to finding server-side request forgery, or SSRF, where a website is tricked into making network requests on the user’s behalf.

In plain words
What is it for?
Authorized testing of remote-image loaders, URL previews, RSS imports, PDF generation, and other features that make requests from the server.
Why use it?
It helps assess URL fetchers, webhooks, PDF generators, and import tools that might reach internal systems, local files, or cloud metadata services.

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

ssrf-methodology 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 4d 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.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
