【悲報】ChatGPTさん、投稿された画像を画像共有サイトに流出させてしまう

ChatGPT's unintended leakage of user‑uploaded images to external image‑hosting sites, as reported by kanasoku.info, highlights a serious privacy breach in OpenAI’s image handling pipeline. For website owners, this incident signals that AI‑driven chat widgets or image‑analysis tools embedded on their pages could become vectors for data exfiltration. If a visitor uploads an image through a ChatGPT integration, the file might be silently forwarded to platforms like Imgur, exposing proprietary visuals, user‑generated content, or even confidential brand assets. This risk amplifies for sites that host user forums, e‑commerce product galleries, or any platform where visual content is central to the user experience. **Actionable steps:** 1. **Audit all ChatGPT or OpenAI API integrations** for image‑upload capabilities; disable or sandbox any endpoints that accept binary data unless you control the storage path. 2. **Update your llms.txt** to explicitly disallow OpenAI’s image‑processing bots from crawling or interacting with pages that contain upload forms: add `User-agent: OpenAI-ImageBot` followed by `Disallow: /upload/`. 3. **Implement server‑side logging and hash‑verification** of every uploaded file to detect unexpected redirects or external POST requests, enabling rapid response if a similar leakage pattern emerges.
