An attacker could exploit this to access or expose your sensitive data, potentially leading to privacy breaches or unauthorized access to personal information.

Compliance Impact

The vulnerability involves an app potentially leaking sensitive user information, which could lead to unauthorized data exposure. This may impact compliance with GDPR (General Data Protection Regulation) by violating principles of data minimization and user consent, and with HIPAA (Health Insurance Portability and Accountability Act) by risking protected health information disclosure.
