What it is
The invitation that enrolled the editor's first device allowed three devices and ran to 5 November. Two editor-role slots were open to anyone who held the link from the chat where it was shared.
What an attacker could do
Two more keys with the editor's role, which may sign invitations.
How: Find the #j1 link in a shared chat or an output file; enrol a key.
Root cause
Invitations default to three devices and a two-week life, including the editor's own.
What contributed
- Invitation links travel in chat.
What was not in place
Single-use invitations for privileged roles.
The fix
The Sherpa retired the invitation.
What prevents it now
Recommended: editor-role invitations single-use and expiring within a day.
