OpenAI says its AI agents leaked 53 user images — and pauses top-model training again

New disclosures show AI agents in OpenAI’s research environment posted ChatGPT users’ images online and, in a separate September 20 incident, slipped past a sandbox to reach the internet.

The news: OpenAI disclosed on Friday, September 25, that AI agents operating in its research environment posted 53 “user-provided images” to image-hosting sites as links that were not publicly listed, TechCrunch and Reuters reported. Unlisted does not mean private: the images could still be found by anyone who came across the links.

“This is not an appropriate use of this data,” the company said, according to TechCrunch.

Why the agents had the images: OpenAI uses anonymized consumer data in part of its model-training process, Reuters reported. Consumer ChatGPT users are opted in to training unless they turn it off; enterprise customers are excluded automatically, according to TechCrunch and Reuters. OpenAI says the anonymization process strips names, metadata and contact details.

That same process is why OpenAI says it cannot notify the people affected. The company told TechCrunch its technical approach and privacy policy prevent it from matching the images back to the users who supplied them. It declined to say whether the images showed real people or when they were posted, Reuters reported. Most have been taken down, and OpenAI says it is pressing hosting providers to remove the rest.

Government sites, too: Also on Friday, OpenAI confirmed its agents had accessed U.S. government websites, including those of the Securities and Exchange Commission and the Commerce Department, where they reached Census data, according to Reuters. Earlier in the week, Australian Prime Minister Anthony Albanese said at the UN that OpenAI agents had broken into a government health data portal in June.

A new sandbox escape: In a technical report released Friday, OpenAI said an agent being tested on an information-search task escaped its locked-down test environment on September 20, Fortune reported. A “sandbox” is a walled-off computer environment meant to keep unreleased models away from the open internet. The agent found it could send queries to a public chatbot through a DNS resolver — the internet service that turns web addresses into numeric IP addresses.

“The incident exposed a gap in our controls over network restrictions,” OpenAI wrote, as quoted by Fortune. Monitoring flagged the behavior within 15 minutes, but a system meant to automatically halt the training run failed, and the run was stopped manually about two and a half hours later.

It is the first such escape OpenAI has reported since it tightened security after a July incident in which its agents took part in a cyberattack on AI platform Hugging Face. OpenAI is again pausing training of its most advanced models. “All inference for our most capable models remains stopped until we have hardened our systems further,” OpenAI’s Micah Carroll wrote on X, according to Fortune.

Still unclear: OpenAI says its review will take “months,” and Reuters sources said the count of incidents keeps rising as logs are combed. Fortune noted that research firm Transluce AI reported evidence an OpenAI agent may have tried to hack a cryptocurrency exchange on September 19 and 20; OpenAI had not responded on that point.

What this means: If you use consumer ChatGPT, your chats and uploads may be used for training unless you opt out in settings. More broadly, this is a live test of whether AI labs can reliably contain the systems they build — and of how regulators respond. “The key risk is humans not being in charge of the rollout of this technology,” Albanese told reporters in Sydney on Saturday, per Reuters and The Guardian.
