Free SQL Injection Scanner
Detect SQL injection indicators in any web page
Enter a URL to scan for SQL injection indicators. This tool fetches the page, analyzes the response body for common database error messages, checks for query parameters that might be injectable, and identifies error-based information leakage from database backends.

How it works
How SQL Injection Scanner works
Enter a URL
Paste any URL — ideally one with query parameters (e.g., ?id=1). We add HTTPS if needed and fetch the page for analysis.
Analyze the response
We scan the HTML response body for common SQL error messages from MySQL, PostgreSQL, MSSQL, Oracle, and SQLite that indicate poor error handling and potential injection points.
Review the assessment
Get a detailed report of any SQL error patterns detected, query parameters found, and an assessment of the application's SQL injection risk profile.
Features
What SQL Injection Scanner checks
Multi-database error detection
Scans for error messages from MySQL, PostgreSQL, Microsoft SQL Server, Oracle, and SQLite — covering the vast majority of database backends used in web applications.
Query parameter analysis
Identifies URL query parameters that could be injection points. Parameters like 'id', 'page', 'user', and 'search' are commonly vulnerable to SQL injection attacks.
Error-based information leakage
Detects when database error messages leak table names, column names, query structure, or database version information that attackers use to craft injection payloads.
Technology stack identification
Identifies the database backend from error message patterns, helping determine which SQL dialect and injection techniques would be applicable.
Use cases
Who should use the free SQL Injection Scanner
Developers
Check your web pages for leaking database error messages. Verify that your error handling properly sanitizes internal database errors before displaying them to users.
Security Engineers
Quickly scan pages with dynamic parameters for SQL injection indicators. Identify applications with poor error handling that could expose database internals to attackers.
Penetration Testers
Use as a first-pass SQL injection indicator during web application assessments. Identify pages that leak database errors and have injectable parameters for deeper manual testing.
