Description OSIDB Bzimport 2026-06-25 11:08:06 UTC 
If Geary is registered as the default mailto handler, any application or website that can open mailto links can silently attach user-readable files to a compose window. The attachment is only visible as an entry in the compose view, which a user may overlook before sending.
