Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects RubyGems packages — download data is not available via public APIs for these ecosystems.

Description

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.
