prevent

Directly prevents SQL injection by validating the ID argument in /display.php against expected formats and rejecting malicious payloads.

SI-2 Flaw Remediation good match
prevent

Requires timely identification, reporting, and correction of the specific SQL injection flaw in /display.php.

SI-9 Information Input Restrictions partial match
prevent

Restricts the format and type of inputs to the ID parameter, limiting opportunities for SQL injection manipulation.
