Railway's new incident report says attackers obtained access to decrypted customer environment variables for at most 1.85% of its workspaces, or approximately 100,000, and generated approximately $740,000 in unauthorized AI usage. The report expands on the cloud hosting provider's October 22 breach disclosure.

Attackers escaped filesystem isolation in build infrastructure, obtained internal source code and exploited a second vulnerability involving an improperly configured trust relationship to reach decryption credentials. Railway says the workspace count is a maximum potential exposure, not confirmed theft from every workspace. It reset exposed linked-account tokens for 1,852 users and says it will cover fraudulent charges that providers decline to refund.
