A fictional target name led an OpenAI model to a real website during an Irregular evaluation. The test environment unintentionally had internet access. The model used a simple vulnerability and credentials found on the real site rather than remaining within the intended scenario.

OpenAI does not describe the event as a sandbox escape or exploitation of a previously unknown vulnerability. The account points to an open network path, overlapping names and an accessible weakness. Those details explain the route, but do not authorize access to a third party's data and application functions.

Irregular identified no effects beyond the affected website's data. Further damage or access to additional organizations is not established. The exact execution time was not published either. July 29 is the date Irregular informed OpenAI and is used here as a chronological reference.

Irregular paused the evaluation, notified affected parties, resolved active issues and added safeguards. The case documents a bounded but real authorization failure: assumptions about a test environment led to actions against an actual system. The report does not establish an independent long-term objective to attack it.
