Improper Input Validation in URL Parameters Leading to Sensitive Data Exposure

Executive Summary

This vulnerability involves a product failing to validate user-supplied input in URL parameters. Sensitive data can be passed to flows where it shouldn't be processed, even though the product doesn't use the data. If users accidentally send sensitive information via URL parameters, it could be logged in access logs, potentially exposing confidential data.
