Name of the Vulnerable Software and Affected Versions
Open WebUI versions prior to 0.10.0
Description
Open WebUI runs client-side Python using Pyodide (a Python distribution for the browser) within a same-origin web worker. This allows stored chat payloads to utilize
pyodide.http.pyfetch, the js module fetch, or XMLHttpRequest APIs to perform authenticated same-origin requests when a user clicks Run. This behavior can be exploited to access admin-only endpoints and execute server-side code via configured tools.Recommendations
Update to version 0.10.0.
