Until this past weekend, a contractor for the Cybersecurity & Infrastructure Security Agency (CISA) maintained a public GitHub repository that exposed credentials to several highly privileged AWS GovCloud accounts and a large number of internal CISA systems. Security experts said the public archive included files detailing how CISA builds, tests and deploys software internally, and that it represents one of the most egregious government data leaks in recent history.

A lesson in how not to respond to vulnerability reports UPDATED Vibe-coding platform Lovable is pooh-poohing a researcher’s finding that anyone could open a free account on the service and read other users' sensitive info, including credentials, chat history, and source code.
