01
The Challenge
The client needed to pass a security compliance review before a payment processor partnership could proceed, but had never had the platform formally tested and had no confidence in its actual security posture.
02
The Approach
1
Ran a structured penetration test covering authentication, session management, input validation, and business logic flaws specific to checkout and payment flows.
2
Identified an IDOR vulnerability allowing access to other customers' order details by manipulating a predictable order ID in the URL.
3
Found a stored XSS vulnerability in a product review field that wasn't sanitizing input before rendering it to other users.
4
Delivered a prioritized remediation plan and implemented the highest-severity fixes directly, then re-tested to confirm closure.
03
The Outcome
All critical and high-severity findings were remediated and verified before the compliance deadline, and the platform passed its payment processor security review on the first attempt.
