plugins/acl/acl-backend-vfile.c in Dovecot 1.2.x before 1.2.15 and 2.0.x before 2.0.5 interprets an ACL entry as a directive to add to the permissions granted by another ACL entry, instead of a directive to replace the permissions granted by another ACL entry, in certain circumstances involving more specific entries that occur after less specific entries, which allows remote authenticated users to bypass intended access restrictions via a request to read or modify a mailbox.

Security readout for executives and security teams

This Dovecot flaw can let a logged-in mail user bypass intended mailbox ACL restrictions. In affected versions, one ACL rule could incorrectly add permissions instead of replacing them, creating unintended read or modify access to a mailbox. Exposure is most likely on legacy Dovecot mail servers running affected 1.2.x or 2.0.x versions with ACL support, especially shared or delegated mailbox environments. Current supported deployments are unlikely to run these versions, but old appliances or unmanaged mail hosts may still exist. Treat as a targeted legacy mail-server exposure. Prioritize remediation if affected Dovecot versions handle sensitive mailboxes or shared mailbox delegation. If no affected versions or ACL usage exist, document non-exposure and monitor only through normal vulnerability management. Mitigation focus: Upgrade Dovecot 1.2.x to 1.2.15 or later.; Upgrade Dovecot 2.0.x to 2.0.5 or later.; Apply fixed distribution packages from Ubuntu, SUSE, Mandriva, or Red Hat where applicable..
