Summary

Open WebUI prior to 0.10.0 runs client-side Python with Pyodide in a same-origin web worker, allowing stored chat payloads using pyodide.http.pyfetch or the js module fetch and XMLHttpRequest APIs to issue authenticated same-origin requests when a victim clicks Run, which can reach admin-only endpoints and execute server-side code through configured tools.

Risk Assessment

An attacker can hijack an admin account or execute arbitrary code on the server, leading to full compromise of the AI platform and potential data leakage.

Recommendation

Immediately upgrade Open WebUI to version 0.10.0 or later. Until then, avoid running untrusted chat payloads and restrict access to the admin panel.
