Report: "PSA Interface Checker — Scary Mistake & Fix"

Summary

A critical defect was discovered in the PSA (Payment Service Adapter / Public Service Announcement — assumed PSA = Payment Service Adapter for this report) interface checker: under specific input conditions the checker failed to validate authentication tokens correctly, permitting malformed or expired tokens to be treated as valid. This created an elevated security risk and potential transaction integrity failures. The issue was promptly fixed by strengthening validation logic, adding layered checks, and improving test coverage.

Introduction

1. Unit Testing: Comprehensive unit testing was performed to ensure the fix did not introduce new errors.
2. Integration Testing: Integration testing was conducted to verify that the updated checker worked correctly with other system components.
3. Simulation-based Testing: Simulation-based testing was used to validate the checker against a range of scenarios, including asynchronous interfaces.
