CVE-2025-5500Public exploit

Credential theft via default Android task affinity

Published Sep 9, 2025 · Updated Sep 9, 2025

Task hijacking in ZhenShi Mibro Fit 1.6.3.17499 allows local users to present a phishing interface when the Android app opens. AndroidManifest.xml leaves taskAffinity at its package-name default, allowing a malicious app to claim com.xiaoxun.xunoversea.mibrofit and place its activity at the root of the shared task. A malicious app must be installed and launched first; subsequent Mibro Fit launches can display the impostor activity and capture sensitive input.
