Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.32%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

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.
