⚠️ Heads-up for mailcow admins:
OS upgrades may install Docker Compose 5.x, which mailcow can run with, but the update script won’t work unless refreshed once.
Fix:
Check your Compose version. If it shows 5.x, you’re affected.
In your mailcow directory: git fetch
Then: git checkout origin/master update.sh
Without this tasks , you can’t update mailcow unless you downgrade Compose to v2 which is harder than running these steps :)
If you still use compose v2 your good to go, simply run an update

While the exploit was not exposed in mailcow environments, updating is still strongly recommended.
