Stored script execution via unsanitized Description markup
Published Jan 8, 2024 · Updated Jun 3, 2025
Stored cross-site scripting in Chanzhaoyu ChatGPT Web 2.11.1 allows remote authenticated users to execute JavaScript via Description. The Description field stores unneutralized image markup, and its onerror handler runs in a browser when the saved page is refreshed. Low-privileged access and a later page view are required; the script runs in the viewer's application origin and can alter displayed content or act within that session.
