exploit-chain

exploit-chain is a skill for Claude Code, Codex from roodlicht/accans-sec-skills. It costs 67 tokens per session (2,620 once invoked), scanned B, original, no licence file.

A security-testing method for combining separate weaknesses into one attack path, such as using an open redirect with OAuth to take over an account.

In plain words
What is it for?
Use it to assemble exploit chains, calculate chain-aware CVSS scores, and map them to MITRE ATT&CK techniques.
Why use it?
It helps assess the combined impact of findings that may appear less serious when viewed separately.

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 B, and why

exploit-chain scanned grade B with 1 finding 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.

Cloud metadata endpointmediumServer-side request forgery

One request to 169.254.169.254 can return temporary IAM credentials.

- **SSRF → Cloud Metadata → Cred leak**. SSRF that does not block DNS resolution to `169.254.169.254` (AWS) or `metadata.google.internal` (GCP) = IAM temporary-credentials extraction.

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
