CVE-2025-52580 is a vulnerability identified in the "region PAY" Android application developed by Gift Pad Co., Ltd. The issue involves the insertion of sensitive user information into application log files in versions prior to 1.5.28. This vulnerability arises because the app improperly logs sensitive data, which can include personal or financial information, into logs accessible on the device. An attacker who gains access to these logs—either through physical access to the device, malware with sufficient permissions, or other means—could extract this sensitive information. The vulnerability does not require user interaction or authentication to be exploited, but the attacker must have access to the application logs, which typically requires local device access or elevated privileges. The CVSS v3.0 base score is 2.4, indicating a low severity primarily due to the limited attack vector (physical or privileged access) and the impact being limited to confidentiality without affecting integrity or availability. No known exploits are currently reported in the wild. The vulnerability was published on July 22, 2025, and affects all versions of the app prior to 1.5.28. The lack of a patch link suggests that users should update to version 1.5.28 or later once available to remediate this issue. This vulnerability highlights the importance of secure logging practices, especially in financial or payment applications where sensitive user data is handled.

For European organizations, especially those involved in financial services or mobile payments, this vulnerability could lead to unauthorized disclosure of sensitive user data if devices running vulnerable versions of the "region PAY" app are compromised. Although the vulnerability requires access to application logs, which limits remote exploitation, the risk remains significant in environments where devices may be lost, stolen, or infected with malware that can access app logs. Exposure of sensitive payment or personal information could lead to privacy violations, regulatory non-compliance (e.g., GDPR), reputational damage, and potential financial fraud. Organizations using or recommending the "region PAY" app should be aware of this risk, particularly in sectors with high regulatory scrutiny or where mobile payment adoption is high. The vulnerability does not affect system integrity or availability, so operational disruption is unlikely; however, confidentiality breaches could have legal and customer trust implications.

1. Immediate update to version 1.5.28 or later of the "region PAY" app once available, as this version addresses the logging issue. 2. Implement device-level security controls such as full-disk encryption, strong authentication, and remote wipe capabilities to reduce the risk of unauthorized access to application logs. 3. Educate users on the risks of installing untrusted applications or granting excessive permissions that could expose app logs. 4. For organizations deploying the app, enforce mobile device management (MDM) policies that restrict access to application data and logs. 5. Monitor for unusual access patterns or malware that could access app logs on devices. 6. Encourage developers to adopt secure logging practices, such as avoiding logging sensitive data and using secure storage mechanisms for sensitive information. 7. Conduct regular security audits and penetration testing on mobile applications to detect similar issues proactively.
