Appium is a cross-platform automation framework for all kinds of apps, built on top of the W3C WebDriver protocol. Prior to 1.1.6, the Appium storage plugin exposes POST /storage/delete, whose handler passes the user-supplied name value directly into path.join(storageRoot, name) and fs.rimraf() without path sanitization, allowing an unauthenticated remote client to escape the storage root with ../ sequences and recursively delete arbitrary writable files or directories. This issue is fixed in version 1.1.6.
