BreachSQL

Context-aware SQL injection scanner — error-based, boolean-blind, time-blind, UNION, and stacked injection detection across MySQL, MariaDB, PostgreSQL, SQLite, MSSQL, and Oracle. WAF detection and evasion built in. No Burp license. Just findings.

pip install breachsql

# from source
git clone https://github.com/CommonHuman-Lab/breachsql.git
cd breachsql
python -m breachsql

Point it at a target. Get findings. Drop it in a pipeline.

Why BreachSQL?

• Multi-technique — error-based, boolean-blind, time-blind, UNION extraction, stacked queries, all in one pass
  • Multi-backend — MySQL, MariaDB, PostgreSQL, SQLite, MSSQL, and Oracle detection and technique selection
• Context-aware — numeric, string, quoted, parenthesised, and header/cookie injection contexts
• WAF-aware — detects common WAFs and applies evasion transforms automatically
• Every injection surface — query params, POST form, JSON body, path parameters, cookies, headers
• Two-step injection — inject at one URL, observe the result at another
• Pipeline-native — JSON output, clean exit codes, Python API

Quick Start

# GET parameter
breachsql -u "https://target.com/item?id=1"

# POST form
breachsql -u "https://target.com/login" -d "username=admin&password=x"

# JSON body
breachsql -u "https://target.com/api/user" -d '{"user_id": 1}'

# Cookie injection
breachsql -u "https://target.com/profile" --cookies "session_id=abc" --cookie-params session_id

# Path parameter
breachsql -u "https://target.com/item/1" --path-params id

# Time-blind with custom threshold
breachsql -u "https://target.com/search?name=x" -t T --time-threshold 3

# Specific backend and technique
breachsql -u "https://target.com/users?id=1" --dbms mysql -t E

# Full multi-technique scan
breachsql -u "https://target.com/report?id=1" --dbms mysql -t EBTUS --level 2 --risk 2

Techniques

Flag	Technique	Description
E	Error-based	Database errors leak schema/data via malformed syntax
B	Boolean-blind	True/false response differences reveal data bit by bit
T	Time-blind	SLEEP() / pg_sleep() / randomblob() timing confirms injection
U	UNION-based	Column-count probing + data extraction via UNION SELECT
S	Stacked	Semicolon-delimited second statement injection

Combine with -t EBTUS to run all techniques in a single pass.

Python API

from breachsql.engine import scan, ScanOptions

result = scan(
    "https://target.com/users?id=1",
    ScanOptions(dbms="mysql", technique="E", risk=1),
)

print(f"{result.total_findings} finding(s) in {result.duration_s:.1f}s")
for f in result.error_based:
    print(f"  [{f.technique}] {f.param} — {f.evidence}")

Options

Option	Default	Description
-u	—	Target to use

--dbms	auto	Target backend: mysql, mariadb, postgres, sqlite, mssql, oracle
-t / --technique	EBTUS	Techniques to run (any combo of E B T U S)
--level	1	Payload depth: 1 = standard, 2 = extended, 3 = extended + data extraction
--risk	1	Payload aggression: 1 = low, 2 = medium, 3 = high
--time-threshold	5	Seconds to consider a time-blind hit (T technique)
-d / --data	—	POST body — form-encoded or JSON
--cookies	—	Cookie string: name=val; name2=val2
--cookie-params	—	Which cookie names to inject
--header-params	—	HTTP header names to inject (e.g. X-Forwarded-For)
--path-params	—	Path segment names to treat as injection points
--second-url	—	Read URL for two-step injection
--timeout	10	Per-request timeout in seconds
-o	—	Write findings to JSON file

Fire Range

The BreachSQL Fire Range is a deliberately vulnerable Flask + MySQL + PostgreSQL + SQLite app that ships with OctoRig (lab slot 7). It provides injectable endpoints that the scanner is verified against on every change.

# Start the Fire Range (OctoRig required)
./octorig.sh start 7

# Run the full end-to-end test suite
pytest tests/test_firerange.py -v

→ Fire Range README

Install from source

git clone https://github.com/CommonHuman-Lab/breachsql.git
cd breachsql
pip install -e .
pip install -e ".[dev]"   # + pytest, mypy, ruff

Requires Python 3.10+. No C extensions.
