What this page helps you understand
SQL injection remains one of the clearest signs that application input is reaching a database unsafely. Fixnx looks for measurable response changes and reports evidence carefully.

SQL injection proof should be measurable
A scanner should not call SQL injection confirmed because a page looks suspicious. It should show what changed: status, response shape, record count, timing, or error behavior.
Fixnx reports SQL injection with evidence summaries and keeps weaker signals marked as likely. That helps developers reproduce the issue without overstating proof.
Use this check especially on search, login, and API filter routes.

FAQ
What makes SQL injection confirmed?
Confirmed SQL injection requires measurable proof such as stable response differences, query errors, record expansion, or verified blind behavior.
Are the payloads destructive?
No. Fixnx uses bounded, controlled payloads intended for safe validation.
