p6-pentest-authz

p6-pentest-authz is a command for Claude Code from jonase47/ccpr. It costs 0 tokens per session (841 once invoked), scanned A, original, MIT.

An authorisation security test for checking whether users can access data or actions that belong to someone else or require higher permissions. It also checks whether protected endpoints can be used without permission.

In plain words
What is it for?
Use it to test IDOR vulnerabilities, horizontal and vertical privilege escalation, and unprotected API endpoints.
Why use it?
It finds access-control mistakes that could expose private data or privileged actions, even when login itself works.

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 A, and why

p6-pentest-authz scanned grade A with 0 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 2d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/p6-pentest-authz – Authorisation & Access Control

Tests IDOR, horizontal/vertical privilege escalation, and unprotected endpoints.

Argument: $ARGUMENTS = [API/area]

If provided: Focus on the specified area. If not provided: Test all protected resources.

Prerequisites

  • /p6-pentest-auth completed
  • RBAC/authorisation implemented

Agent

  • Type: pentester
  • Model: sonnet

Context (Orchestrator prepares)

Orchestrator reads in advance and delivers inline:

  • From src/: Authorisation code (middleware, guards, ownership checks)
  • From API_SPEC.md: Protected endpoints and permission matrix
  • From SECURITY.md: Authorisation requirements

Prompt Template

Goal: Actively test authorisation for vulnerabilities in: [area]

Authorisation Code: [inline from src/]

Permission Matrix: [inline from API_SPEC.md / SECURITY.md]

Output Format: Table with max. 10 attack attempts:

# Attack Method Result Severity PoC

Types: IDOR, Horizontal Escalation, Vertical Escalation, Unprotected Endpoints

Constraints:

  • Authorisation attacks ONLY – no auth, no injection
  • PoC minimal and non-destructive
  • For missing authorisation (e.g. single-user app): "N/A" is sufficient

Orchestrator Checkpoint

  • IDOR and privilege escalation tested?
  • All protected endpoints checked?

Write Detail File

Write the result to docs/quality/pentest_authz.md (overwrite). Frontmatter:

---
phase: P6
subskill: pentest-authz
status: active
last_updated: <DD.MM.YYYY>
---

Body sections: ## Scope, ## Findings (authz/IDOR/privilege-escalation table with PoCs), ## Severity Summary.

Update Sub-Index

Update docs/quality/PENTEST.md:

  • Set **Last Updated:** <DD.MM.YYYY>.
  • In its Detail Files table: ensure a row for [pentest_authz.md](pentest_authz.md) with status complete.
  • Lift any privilege-escalation finding into Open Risks as Critical.

Handover Epilogue

Before writing. docs/HANDOVER.md is capped — the file states its own limit in its header (default: ≤5 KB / ~150 lines). Two rules follow from that, and neither is optional:

  • Replace this command's previous epilogue block, do not append a second one. Stacking is what pushes the file over; one skill run has been measured adding 1021 B, ~20 % of the cap.
  • If the file is already near its cap, shorten before you add. Reading the cap sentence is not the same as measuring: check the actual size, and when there is no room, condense existing content or hand the user /cleanup instead of growing the file further.

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.
