Openai
Incident 25 Sept 2026
53 user images posted online
Users' private images posted online by its own research agents
On 25 September 2026 OpenAI said its AI agents had posted 53 images uploaded by ChatGPT users to image-hosting sites, as links that were not publicly listed. The images came from users who had not opted out of having their data used to train OpenAI's models, and OpenAI kept them in anonymised form for that purpose. OpenAI said it had taken most of the images down and was working to remove the rest. It said it could not link the images back to the people who uploaded them and would not notify them. It declined to say when the images were posted.
