idor-to-priv-esc

idor-to-priv-esc is a skill for Claude Code, Codex from MingyiSecLab/Mingyi-Atlas. It costs 22 tokens per session (96 once invoked), scanned A, a copy of chain-idor-to-priv-esc, Apache-2.0.

A security testing guide for linking IDOR—access to another user's record by changing an object identifier—to privilege escalation and administrator-level actions.

In plain words
What is it for?
Testing object access, role and permission changes, recovery-token access, and the resulting privileged actions.
Why use it?
It helps show whether a reference to someone else's object can change permissions, expose recovery data, or control sensitive settings.

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

idor-to-priv-esc 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 12d 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.

Origin

This is a copy

89% identical to chain-idor-to-priv-esc — 5 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Chain: IDOR to Privilege Escalation

Canonical path

  1. IDOR modifies another user's sensitive object.
  2. Escalate role/permissions or steal recovery token.
  3. Perform admin-level action and show impact.

Validation

Demonstrate before/after authorization state and downstream privileged action evidence.

Changes

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.
