CVE-2025-57789
During the brief window between installation and the first administrator login, remote attackers may exploit the default credential to gain admin control.
Does this matter?
Lower severity and a low EPSS score (1.23%). Track it; it rarely justifies an emergency change on its own.
Description
During the brief window between installation and the first administrator login, remote attackers may exploit the default credential to gain admin control. This is limited to the setup phase, before any jobs have been configured.
