How to Retest a Security Finding After a Web Application Rewrite

A rewritten application may remove old vulnerable code but introduce new routes or behavior. Closing findings based only on a different version number does not confirm the original weakness is gone.

What to check

Map the finding to the new route and component, reproduce the original test within authorized scope, and review changed authentication, input handling, and dependencies. Confirm the scanner can reach the relevant feature.

Recommended next step

Retest the specific weakness and document the evidence and any changed attack surface. Keep related findings open until their underlying risk is addressed, even if the original endpoint no longer exists.
