hunt-sqli

hunt-sqli is a skill for Claude Code, Codex from uphiago/recon-skills. It costs 136 tokens per session (6,106 once invoked), scanned A, original, MIT.

A security-testing guide for injection flaws in database queries, including SQL databases and document databases such as MongoDB. The flaw occurs when user input changes the meaning of a query.

In plain words
What is it for?
Use it to test web forms and APIs that search, filter, sort, authenticate users, look up records, or pass input through database libraries and query builders.
Why use it?
It helps find endpoints where search terms, filters, sorting, login fields, or identifiers are inserted into queries unsafely. An attacker may then read, change, or delete data.

SkillSpector: 2 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high YARA Match · line 209
    YARA rule matched a hack tool or exploit indicator (offensive tools, reconnaissance, privilege escalation, or exploit frameworks).
    Fix: Remove offensive tool references and exploit code. Legitimate agent skills should not contain penetration testing tools, exploit frameworks, or reconnaissance utilities.
  • medium Data Exfiltration · line 440
    Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
    Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.

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

hunt-sqli scanned grade A 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 7d 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.

When to Use

Use when the target has any endpoint that interacts with a database — search, filter, sort, login, ID-based lookups, API parameters, or any user input that could be used in a query. SQL injection (including NoSQL injection) remains one of the highest-paying vulnerability classes because it directly threatens data confidentiality, integrity, and availability. Every parameter in GET/POST/JSON/headers/cookies that reaches a backend database is a candidate. Highest-value targets: multi-tenant SaaS platforms, e-commerce/payment systems, search endpoints, analytics subdomains, and third-party plugins.

Crown Jewel Targets

SQL injection remains one of the highest-paying vulnerability classes in bug bounty because it directly threatens data confidentiality, integrity, and availability at scale.

Highest-value targets:

  • SaaS platforms with multi-tenant databases — one injection can expose all customer data
  • E-commerce/payment systems — PII, card data, transaction records
  • Search endpoints — user-controlled input passed directly to queries (e.g., Rockstar Games /search)
  • Analytics/tracking subdomains — often built fast, tested less (e.g., sctrack.email.[RIDESHARE_CO].cn)
  • Third-party plugins on enterprise installs — WordPress plugins, CMS extensions running on corporate domains (Uber's Huge IT Video Gallery)
  • Internal tooling exposed externally — Apache Airflow, GitHub Enterprise, admin dashboards
  • NoSQL backends (MongoDB) — often overlooked, same injection class, different syntax

Asset types that pay most:

  • Production APIs with /search, /filter, /sort, /report parameters
  • Subdomains with legacy stacks (.cn, .co, .io regional variants)
  • Self-hosted open-sourcetools (Airflow, GitLab, Jenkins) on bounty scope
  • Email tracking and analytics infrastructure

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.
