sqli-sql-injection

sqli-sql-injection is a skill for Claude Code, Codex from SecurityTalent/bugskill-ai. It costs 39 tokens per session (4,232 once invoked), scanned A, a copy of sqli-sql-injection, MIT.

A security-testing guide for SQL injection, where crafted input changes a database query instead of being treated only as data.

In plain words
What is it for?
Use it to inspect application inputs that reach SQL queries, including blind cases where the database gives no visible error and second-order cases triggered later.
Why use it?
It helps find unsafe handling of input in login checks, searches, filters, reports, and database-specific query paths.

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

sqli-sql-injection 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 1mo 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.

SKILL: SQL Injection — Expert Attack Playbook

AI LOAD INSTRUCTION: Advanced SQLi techniques. Assumes basic UNION/error/boolean-blind fundamentals known. Focuses on: per-database exploitation, out-of-band exfiltration, second-order injection, parameterized query bypass scenarios, filter evasion, and escalation to OS. For real-world CVE cases, SMB/DNS OOB exfiltration, INSERT/UPDATE injection patterns, and framework-specific exploitation (ThinkPHP, Django GIS), load the companion SCENARIOS.md.

  • ghost-bits-cast-attack when the backend is Java with Jackson and your SQL keywords are WAF-blocked — Jackson's charToHex table is indexed by ch & 0xFF, so a Unicode character like 丰 (U+4E30) resolves to hex digit 0 inside a \uXXXX escape sequence, letting you smuggle UNION, SELECT, 1, etc. without the WAF ever seeing them

1. QUICK START

Extended Scenarios

Also load SCENARIOS.md when you need:

  • SMB out-of-band exfiltration via LOAD_FILE + UNC paths (Windows MySQL)
  • KEY injection / URI injection / non-parameter injection points
  • INSERT/DELETE/UPDATE statement injection differences
  • ThinkPHP5 array key injection (updatexml error-based)
  • Django GIS Oracle utl_inaddr.get_host_name CVE
  • ORDER BY / LIMIT injection techniques

Advanced Reference

Also load SQLMAP_ADVANCED.md when you need:

  • SQLMap tamper scripts matrix and WAF bypass tamper chain recipes (space2comment, between, charencode, etc.)
  • --technique, --risk/--level combinations and --second-url for second-order injection
  • --os-shell / --os-pwn OS-level exploitation via SQLMap
  • INSERT/UPDATE/DELETE injection patterns with data exfiltration examples
  • GraphQL + SQL injection (batched queries, nested field injection, mutation injection)
  • DB-specific advanced functions: PostgreSQL dollar-sign quoting, MSSQL linked servers, Oracle DBMS_PIPE/DBMS_SCHEDULER

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.
