Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

An issue was discovered in cyrus-imapd in Cyrus IMAP through 3.12.2. The LOCALDELETE command bypassed ACL checks. An authenticated but non-admin user could invoke the admin-only LOCALDELETE IMAP command and delete mailboxes for which they had no permissions.

This bug appears to have been reported against 'rawhide' during the Fedora Linux 45 development cycle.
Changing version to 45.
