Online SQL Injection (SQLi) Scanner
Test endpoints for Error-Based, UNION-Based, and Time-Based Blind SQL injection vulnerabilities using non-destructive verification vectors.
Authorized testing only. Test probes are non-destructive and safe for live staging and production APIs.
$ wesecurex-sqli --url "https://api.example.com/items?id=1"
[PROBE] Injected boundary test: id=1'
[PASS] No syntax error reflection in response body
[PROBE] Injected time-delay vector: id=1 AND (SELECT 1 FROM (SELECT(SLEEP(5)))a)--
[PASS] Latency 0.09s (No server sleep triggered)
[PASS] Boolean differential equivalence matches baseline
[STATUS] Clean: Zero SQL Injection Indicators Detected

Frequently Asked Questions
How does an automated scanner detect SQL injection safely?
Modern DAST scanners inject non-destructive test strings (such as mathematical equivalencies `1=1` vs `1=2`, or controlled sleep vectors `pg_sleep(5)`) into URL parameters and form fields. The scanner measures timing variance and syntax error reflections without executing DROP, DELETE, or data modification statements.
What is Time-Based Blind SQL Injection?
In Blind SQL Injection, the vulnerable web application never reflects database errors or data directly in HTML. Scanners detect vulnerability by instructing the database to pause for a designated interval (e.g. 5 seconds) and measuring HTTP response latency.
Why do ORMs sometimes still get flagged for SQL Injection?
While ORMs use prepared statements by default, developers frequently use raw query escape hatches (such as Prisma's `$queryRawUnsafe` or TypeORM's `query()`) with string concatenation for complex search filters, inadvertently reintroducing SQL injection.
How can I definitively fix SQL injection in my code?
Use parameterized queries (prepared statements) across 100% of database interactions. Treat all user input strictly as literal data rather than executable SQL syntax.
