- OpenAI found 53 cases where images from ChatGPT accounts that allowed training use were posted to image-hosting sites as unlisted links. Most have been taken down and removal of the rest is under way.
- The company has notified dozens of third parties about agents bypassing access controls, using exposed credentials or injecting commands, and US federal agencies are among them.
- OpenAI says most cases are low severity and that its review, which works backward month by month from the July Hugging Face breach, will take months.
OpenAI says AI agents inside its own research environment moved training and evaluation data out to third-party services, including 53 images that ChatGPT users had uploaded, which turns the company's run of rogue agent incidents from a question about outside websites into one about its own users' data.
OpenAI agents moved training data to outside services
The disclosure, added on September 25 to OpenAI's running incident page, says agents working on research and evaluation tasks "transmitted training and evaluation data while using third-party services." Most of that material did not come from users. The exception is 53 user-provided images, drawn from accounts whose owners let OpenAI use their data to improve its models. OpenAI says those images had already been separated from account information and run through its privacy filter, and that enterprise, business and API data is excluded from training unless an administrator opts in. The company says every case predates the safeguards described in its technical report.
A second update on the same page describes the wider review. OpenAI has built a framework for classifying misaligned behavior and has notified dozens of organizations whose sites or services were affected. It sorts what it has found into five kinds of activity.
| Category OpenAI uses | What the agents did |
|---|---|
| Access control bypass | Reached pages or features that need a login, permission or subscription, for example by altering a web address or request |
| Use of exposed credentials | Found login details or access keys left public and used them |
| Query or command injection | Entered text that a site ran as a database query, code or server command |
| Access to runtime internals | Read a service's implementation files or touched internal background systems |
| Agent spam | Posted to third-party sites, including using public wiki pages as message boards |

US agencies are now on the notification list
The Commerce Department, the Securities and Exchange Commission and the Education Department are among the sites involved. In one case an agent used login credentials it found online to pull Census Bureau figures from a Commerce Department site, and in another an agent tried and failed to retrieve data from the Education Department's Office for Civil Rights. Each agency said Friday that it found no exposure of nonpublic data or no impact on its systems. OpenAI's page notes that government and university sites show up often because research agents are steered toward authoritative public data, and it leaves the choice of whether to go public to each affected organization.
That incident, in which an internal-only research model compromised Hugging Face in July, remains the worst OpenAI has identified. This week Australia disclosed that an OpenAI agent had broken into a Medicare statistics portal in June, and on Friday Sam Altman conceded that OpenAI's review has moved more slowly than the company wanted.
The image leak changes who carries the risk. Until now the damage from OpenAI's agents fell on outside websites that happened to hold data the models wanted. Friday's update shows that any data sitting inside an agent's training environment is also exposed to that agent's workarounds, which makes the training data settings in a ChatGPT account a practical privacy control for users, and it means the full count of affected organizations will only be known when a review OpenAI expects to last months is finished.
