Frequently Asked Questions
What patterns get flagged?
Tautologies (' OR '1'='1), UNION selects, stacked queries (; DROP), comment truncations (--), and time-based payloads (SLEEP/WAITFOR). Each flag names the technique.
Does clean mean safe?
No — pattern scanning catches known shapes, not logic flaws or second-order injection. Parameterized queries plus least-privilege DB users are the real fix; this is a tripwire.
False positives?
Yes on prose containing quotes and SQL keywords (O'Brien, 'select committee'). Review flags in context — legitimate text trips naive patterns.
Is scanned input uploaded?
No — matching runs locally in your browser. Inputs never leave your device.
