To find business logic flaws in PHP applications, trace data flows and state changes across authentication, authorization, and workflows to collect evidence of mass assignment, race conditions, and timing issues.

A mass assignment vulnerability in PHP occurs when user input binds directly to model attributes, allowing privilege escalation. Detect it by tracing data flows to identify unguarded properties and generating proof-of-concept payloads.

Testing for race conditions and TOCTOU risks in PHP workflows involves tracing timing-sensitive state transitions to uncover bypass paths, collecting evidence of inconsistent state handling, and delivering remediation guidance.

Yes, you can audit authorization bypass and privilege escalation in PHP codebases by tracing business workflows to identify unvalidated state transitions and gaps in authentication checks, producing severity levels and fixes.

The best way to generate PoCs and remediation guidance for PHP security audits is to trace data flows and state changes to collect evidence chains, then deliver severity levels and targeted fixes for identified logic flaws.
