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

The session cookie store implementation in Spree 0.2.0 uses a hardcoded config.action_controller_session hash value (aka secret key), which makes it easier for remote attackers to bypass cryptographic protection mechanisms by leveraging an application that contains this value within the config/environment.rb file.
