Description OSIDB Bzimport 2026-03-20 16:03:17 UTC 
The webbrowser.open() API would accept leading dashes in the URL which 
could be handled as command line options for certain web browsers. New 
behavior rejects leading dashes. Users are recommended to sanitize URLs 
prior to passing to webbrowser.open().
