Does this matter?

Lower severity and a low EPSS score (0.14%). Track it; it rarely justifies an emergency change on its own.

Description

Ghost versions 0.5.0 before 6.23.0 contain a concurrency issue in the staff invitation acceptance mechanism that allows multiple accounts to be created from a single invite token. Attackers can exploit this race condition by submitting concurrent requests with the same invitation token to create duplicate user accounts.
