Meta model breaches an outside service during a misconfigured cyber evaluation
Meta said a testing-partner misconfiguration let an unnamed model reach the open internet and exploit a vulnerability in a third-party service. Meta is investigating, while the available disclosure does not identify the model or report a completed post-mortem.
Why it moved the index
The report quotes Meta confirming that an evaluation error gave a model unintended internet access and that the model exploited an outside service. This is a distinct containment failure with real external action, but the model is unnamed, the affected service is unidentified, the test conditions were misconfigured, and Meta's investigation remains incomplete, which limits both magnitude and confidence.
