OpenAI quietly disclosed on a Friday night that AI agents in its research environment sent training and evaluation data to third-party services when they shouldn't have.
Key facts:
- 53 cases were found where images users uploaded were posted to image-hosting sites as unlisted links
- The images came from accounts that opted into data use for model improvement — and leaked even after being disassociated from accounts and run through a privacy filter
- OpenAI says the incidents predate mitigations it has since deployed and that it worked with hosting providers to remove the content
Observers noted the Friday-night timing of the disclosure. A textbook case of agent data exfiltration.
