Does this matter?

Lower severity and a low EPSS score (0.26%). Track it; it rarely justifies an emergency change on its own.

Description

Ghost versions before 6.62.0 contain an authentication bypass vulnerability in staff invite acceptance that allows users to specify any email address when creating their account. Attackers can accept leaked invite tokens with attacker-controlled email addresses, or legitimate recipients can register with unintended email providers.
