That was my thought exactly. Agent broke in, read some files (no mention of PII or confidential things) to confirm read access, dropped a test file to confirm write access, sent an email explaining that's bad with a few details.

“We are notifying you of a security vulnerability identified during our review of OpenAI Model activity…” the communiqué began. “An OpenAI model identified a way to make the server carry out instructions sent through the public reporting interface, without a private account or password.”

“It was able to access this to read portions of internal program files and settings, obtain a list of files, and create and read back a small test file on the server,” it explained. “Our review found no evidence that the model accessed patient-level records, personal information or credentials; deleted data; or established ongoing access.”

Being on the defensive side myself, if I received that from a human I'd be grateful.

Edit: from the bad screenshot, the email was even sent to the right email: "PUBLIC DISCLOSURE". So the target does accept such reports.
