Description
SailingLab AppLock (aka com.alpha.applock) 4.3.8 for Android allows a local attacker to trigger arbitrary JavaScript execution via BrowserMainActivity, which accepts VIEW intents with javascript: URIs. This unsafe navigation path results in script execution and may allow UI spoofing or privilege escalation.
