CVE-2018-3760 — Vulnerability in sprockets — CVE Details

HIGH

Sprockets path traversal leads to information leak

Published June 20, 2018Updated February 16, 2024Source: osv

Summary

Specially crafted requests can be used to access files that exist on the filesystem that is outside an application's root directory, when the Sprockets server is used in production. All users running an affected release should either upgrade or use one of the work arounds immediately. ### Workaround: In Rails applications, work around this issue, set `config.assets.compile = false` and `config.public_file_server.enabled = true` in an initializer and precompile the assets. This work around will not be possible in all hosting environments and upgrading is advised.
