What it does
Best practices for Android Intent security. Use this skill when auditing component configurations in AndroidManifest.xml activities, services, receivers) or source code handling incoming Intents (getIntent, getParcelableExtra) to prevent Intent Redirection and unauthorized access.
This skill provides guidelines and patterns to secure Android components (Activities, Services, Broadcast Receivers, Content Providers) and handle Intents safely, preventing privilege escalation and unauthorized access.
Glossary
- Intent: An asynchronous messaging object used to request an action from another app component.
- Exported component: A component (
android:exported="true") that can be launched by other apps on the device. - Sticky intent: A broadcast intent that remains in the system cache after it's sent, allowing any app to retrieve its contents.
- Signature permission: A permission whose protection level is set to
signature, granted only to apps signed with the same developer key. - onNewIntent: An activity lifecycle callback invoked when an activity is launched with
FLAG_ACTIVITY_SINGLE_TOPand is already running at the top of the history stack. - PendingIntent: A token granted to a foreign application (for example, system services) allowing it to execute a predefined Intent with the creator's permissions.
- Mutable PendingIntent: A PendingIntent whose underlying Intent parameters can be modified by the receiving application.
- ContentProvider: A component that encapsulates data and provides it to other applications via standard query/insert interfaces.
- IntentSanitizer: A utility class in AndroidX Core used to build a safe, sanitized copy of an incoming Intent by filtering out unauthorized components, actions, or extras.
- Intent redirection (forwarding): A vulnerability where an application receives an intent from an untrusted source and uses it to launch a private, non-exported component.
