Mitigate supply-chain attacks with bundle cooldown#975
Merged
Conversation
Introduces the new time-based 'cooldown' filter shipped in Bundler 4.0.13. Most supply-chain attacks exploit a tiny window immediately after a gem version is published. This feature prevents Bundler from resolving to any gem version until it has been public for a minimum number of days, allowing time for community vetting.
