CVE-2025-9135Public exploit

Credential theft via Android task hijacking

Published Aug 19, 2025 · Updated Sep 13, 2025

Task hijacking in SmartRide, cleVVVer mobil, BusBahnBim, and Salzburg Verkehr 12.1.1(258) and earlier allows local users to display phishing UI. AndroidManifest.xml leaves the default task affinity in place, allowing a malicious app to claim the same affinity and place its activity at the root of the victim app's task stack. Exploitation requires a malicious app on the same Android device and user interaction with both apps, enabling credential or sensitive-data theft.
