## FAQ

### What does this mean?

A locally installed app can change the Forkyz app's stored settings without any user interaction. For example, it can rewrite the Storage Location setting to a caller-supplied URI without validation.

### Am I affected, and how do I check?

The listed affected build is Forkyz (app.crossword.yourealwaysbe.forkyz) version 8500000 for Android, where the ForkyzSettingsImporter activity is exported with no permission. To check the installed build, look at the app's version code in the Android package information for app.crossword.yourealwaysbe.forkyz.

### What should I do about it?

The checked facts do not name a fixed version, so no upgrade target can be given. Check the Forkyz release page for a newer build than version code 8500000.

### Is it being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. CISA's SSVC assessment notes a proof of concept exists. No public exploit code is tracked.

### What if there's no patch?

The checked facts do not describe a workaround. No fix is recorded, so the only option the facts support is to watch for a fixed release.
