CVE-2026-27115Public exploit

Arbitrary directory deletion via unvalidated launch path

Published Feb 20, 2026 · Updated Feb 20, 2026

Path traversal in Alex4SSB ADB Explorer before 0.9.26021 allows local users to delete directory trees through a crafted launch argument. App.xaml.cs accepts an existing first-argument directory as Data.AppDataPath, after which ClearDrag recursively deletes every subdirectory at startup and exit. Exploitation requires a user to launch a crafted shortcut, batch file, or script; deletion bypasses the Recycle Bin and is limited by that user's filesystem permissions.
