Description OSIDB Bzimport 2026-10-05 10:50:19 UTC 
The email media type OAuth form passes the Authorization endpoint value to window.open() without validating the URL scheme, so a javascript: URL is executed in the browser. This means a crafted media type configuration, deliverable as an import file, runs arbitrary JavaScript as the Super Admin who grants consent.
