Title

Improper Link Resolution in Okta Verify for Windows Uninstaller Data Removal

Summary

The Okta Verify for Windows uninstaller does not verify whether the user data directory is a filesystem junction before deleting its contents with elevated privileges. The delete operation follows the junction target, resulting in recursive deletion of unintended directory contents.

Severity
