Mercedes-Benz source code exposure

An employee committed a token to a public repo. It gave unrestricted and unmonitored access to the entire source code on the internal GitHub Enterprise Server, exposing database connection strings, cloud access keys, blueprints, design documents, SSO passwords, and API keys. The first token granted full ownership of the account; inside one of its private repos sat a second token to the GHE instance, a classic chained-credential blast radius that ran from the user plane straight into the enterprise plane.
