Résumé
mailcow: dockerized vulnerable to stored XSS in Quarantine attachment filenames
Description d'origine
La description telle que publiée par la source (souvent en anglais).
mailcow: dockerized is an open source groupware/email suite based on docker. In versions prior to 2026-03b, the Quarantine details modal injects attachment filenames into HTML without escaping, allowing arbitrary HTML/JS execution. An attacker can deliver an email with a crafted attachment name so that when an admin views the quarantine item, JavaScript executes in their browser, taking over their account. Version 2026-03b fixes the vulnerability.
