exploiting-idor-vulnerabilities
by mukul975exploiting-idor-vulnerabilities helps authorized security audits test Insecure Direct Object Reference flaws across APIs, web apps, and multi-tenant systems with cross-session checks, object mapping, and read/write verification.
This skill scores 78/100, which means it is a solid directory candidate: users can likely trigger it correctly and get real IDOR-testing value, though they should expect some completeness gaps in surrounding docs. The repository provides a concrete authorized-testing workflow, a runnable Python agent, and API reference material, making it more decision-useful than a generic prompt.
- Concrete IDOR workflow with explicit authorized-use cases, prerequisites, and testing steps.
- Runnable support material: a Python script plus API reference for horizontal, vertical, enumeration, cross-session, and write-based checks.
- Strong triggerability signals from clear frontmatter, domain tags, and repo-linked usage examples.
- No install command in SKILL.md, so setup/activation may require more manual interpretation than an ideal directory listing.
- The preview suggests code-heavy guidance but limited high-level scope framing, which may leave users unsure which applications or endpoints are the best fit.
Overview of exploiting-idor-vulnerabilities skill
What this skill does
The exploiting-idor-vulnerabilities skill helps you test whether an application exposes Insecure Direct Object Reference paths that let one user access another user’s data. It is aimed at authorized security work, especially when you need a repeatable way to check object-level authorization on APIs, web apps, and multi-tenant systems.
Who it is for
Use the exploiting-idor-vulnerabilities skill if you are doing a penetration test, bug bounty review, or internal security audit and need to validate access control with real requests rather than a generic prompt. It is most useful when endpoints use predictable IDs, and when you can compare behavior across two accounts or privilege levels.
Why it is worth installing
This skill is more decision-oriented than a basic IDOR checklist: it gives you a workflow for mapping object references, comparing cross-session responses, and testing both read and write paths. That makes the exploiting-idor-vulnerabilities skill install more attractive when you want a practical guide for finding broken authorization, not just a definition of IDOR.
How to Use exploiting-idor-vulnerabilities skill
Install and first files to read
Install the exploiting-idor-vulnerabilities skill in your skills environment, then read SKILL.md first for the workflow and prerequisites. After that, inspect references/api-reference.md for the Python testing interface and scripts/agent.py for the implementation details behind the CLI and response comparison logic.
What input the skill needs
The exploiting-idor-vulnerabilities usage flow works best when you provide a target base URL, two authenticated sessions or tokens, a short list of suspect endpoints, and one known resource you own plus one you should not access. For example, a strong prompt includes paths like /api/v1/users/{id}/profile and /api/v1/orders/{id}, not just “test my app for IDOR.”
Practical workflow to follow
A good exploiting-idor-vulnerabilities guide starts by inventorying object references, then checking whether the same request behaves differently across users. Use the skill to test horizontal cases first, then vertical access checks, then write operations such as PUT or PATCH, because many IDOR issues show up only when the application accepts changes, not just reads.
Example prompt shape
If you want the skill to trigger cleanly, ask for a narrow outcome: “Review these endpoints for IDOR risk, compare responses for user A and user B, and report any object-level authorization gaps.” That is better than asking for a generic “security audit,” because the exploiting-idor-vulnerabilities for Security Audit use case depends on concrete endpoints, IDs, and user context.
exploiting-idor-vulnerabilities skill FAQ
Is this for offensive abuse or authorized testing?
The exploiting-idor-vulnerabilities skill is framed for authorized testing only. It is appropriate for internal audits, bug bounty scopes, and lab environments, not for unauthorized access attempts.
Do I need Burp Suite to use it?
Burp Suite is recommended in the source material, especially for manual request replay and cross-session comparison, but the skill is not limited to Burp. If you already have curl, httpie, or a scripted HTTP client, you can still use the same testing logic.
How is this different from a normal prompt?
A normal prompt might explain what IDOR is. The exploiting-idor-vulnerabilities skill is more useful when you need an execution path: identify endpoints, test with two identities, compare responses, and document whether object-level authorization is enforced consistently.
Is it beginner-friendly?
Yes, if you already understand basic HTTP requests and can work with at least two accounts. It is less suitable if you do not have permission, cannot obtain test credentials, or do not know which endpoints expose object IDs.
How to Improve exploiting-idor-vulnerabilities skill
Give the skill sharper targets
The biggest quality jump comes from providing exact endpoints, verbs, and identifier patterns. For example, “GET /api/v2/invoices/{id} and PATCH /api/v2/invoices/{id}” is far more useful than “check invoices,” because the skill can reason about read versus write IDOR separately.
Provide a clean comparison baseline
To get better results from the exploiting-idor-vulnerabilities skill, include one resource you definitely own, one you definitely do not own, and the expected status code or content differences. That helps the analysis spot real authorization failures instead of normal variation in error pages or empty records.
Watch for the common failure modes
The most common miss is testing only one endpoint or only one account. Another is assuming a 403 on a UI page means the API is protected too; the skill works better when you test the actual API path, the parameterized route, and any alternate write endpoint that touches the same object.
Iterate after the first run
After the first pass, expand only the neighboring object types that share the same access pattern, such as profiles, invoices, tickets, or file downloads. For the exploiting-idor-vulnerabilities skill, the best improvements come from adding endpoints and session comparisons, not from asking it to “be more thorough” without new evidence.
