CVE-2018-3760: Information Exposure

June 26, 2018 (updated July 1, 2024)

The package sprockets may leak confidential information. Specially crafted requests can be used to access files that exist on the filesystem that are outside an application’s root directory when the server is used in production. All users running an affected release should either upgrade or use one of the work arounds immediately.
