What is CVE-2026-77875?

The Calculator Lock application by MACY Mind utilizes a calculator-style vault passcode to secure access. However, vulnerabilities arise when the stored data is not adequately bound to this authentication mechanism. An attacker with local access to shared external storage can exploit this flaw, gaining the ability to copy the SQLite database and media files directly without needing to authenticate through the vault's passcode. This can lead to unauthorized access to sensitive information, highlighting the essential need for improved security measures in data protection.

Affected Version(s)

Hide Photos - Secure vault Android 4.1.0
