n8n had some serious security bugs this month that could let hackers break into certain n8n servers and steal or use the keys stored inside (like API keys and logins). The good news is: these issues have fixes. If you’re using the official n8n Cloud, they handle updates for you, and if you’re running n8n yourself on any cloud server, the main thing is to update n8n to the newest version so you’re on the patched, secure release.
If your n8n was old and reachable from the public internet, it’s also a good idea to change any important keys and passwords you stored in it, just in case someone copied them before you updated. You don’t need to know dev ops or databases for this: ask your hosting provider or tech person to “update n8n to the latest secure version and then rotate (change) all the secrets it uses.”
I’ll include a link to a full article if you want more detail and screenshots.
