CVE-2021-32056
Cyrus IMAP before 3.2.7, and 3.3.x and 3.4.x before 3.4.1, allows remote authenticated users to bypass intended access restrictions on server annotations and consequently cause replication to stall.
Does this matter?
Lower severity and a low EPSS score (1.70%). Track it; it rarely justifies an emergency change on its own.
