**Name of the Vulnerable Software and Affected Versions** Pallets Werkzeug versions prior to 0.15.5 **Description** The issue is related to how SharedDataMiddleware handles drive names, such as C:, in Windows pathnames. This mishandling can lead to potential security issues. **Recommendations** For versions prior to 0.15.5, update to version 0.15.5 or later to resolve the issue. As a temporary workaround, consider restricting access to the SharedDataMiddleware to minimize the risk of exploitation.
