CVE-2026-40872 is a critical cross-site scripting (XSS) vulnerability in mailcow-dockerized versions prior to 2026-03b. The vulnerability arises because the admin dashboard's Autodiscover logs render the EMailAddress value without HTML escaping, allowing an attacker to submit a crafted email address containing malicious HTML or JavaScript. This payload is stored in Redis and executed when an admin views the Autodiscover logs. The issue is fixed in version 2026-03b.
