Description OSIDB Bzimport 2026-07-16 19:01:24 UTC 
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.
