CVE-2026-59214
Last modified
CVE-2026-59214 is a critical-severity vulnerability rated 9/10 on the CVSS scale. Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. Prior to 0.10.0, Open WebUI runs client-side Python with Pyodide in a same-origin web worker, allowing stored chat payloads that use 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. EPSS estimates a 0.25% chance of exploitation in the next 30 days.
