CVE-2026-77875Public exploit

Local vault data disclosure via shared storage

Published Sep 18, 2026 · Updated Sep 18, 2026

Insecure storage in QUANTUMTECH LTD Hide Photos - Secure vault 4.1.0 allows local users to read vault data from shared storage. The app writes media and a SQLite wallet database to the predictable /storage/emulated/0/.Calculator_dont_delete_me path and stores sensitive fields as reversible Base64 rather than encrypting them. Access to shared external storage, such as an authorized non-root ADB shell, exposes photos, passwords, PINs, and notes without the vault passcode.
