Description
mailcow-dockerized contains a stored cross-site scripting vulnerability in the administrator Queue Manager. The Queue Manager fetches mail queue entries from /api/v1/get/mailq/all, copies server-controlled Postfix queue fields into DataTables rows, and renders several of those fields as HTML without adequate output encoding.
This issue affects mailcow-dockerized: 2026-03b.
