Description

mailcow: dockerized is an open source groupware/email suite based on docker. An unauthenticated attacker can inject a JavaScript payload into the API logs.

This could lead to unauthorized actions, data theft, or further exploitation of the affected system. This issue has been addressed in the `2024-07` release. All users are advised to upgrade.
