The n8n Clusterfuck of a Vulnerability – Because Why the Hell Not?

Well, congratulations to the poor sods maintaining n8n, the darling of workflow automation. They’ve managed to gift the internet yet another steaming pile of security negligence. This isn’t your run-of-the-mill “oopsie” bug either — oh no, this beauty scores a glorious 9.9 CVSS. That’s basically “run for your bloody lives” territory. It lets authenticated users (you know, the folks you supposedly trust) execute system commands straight on your server. Because who needs security boundaries when you can have chaos?

So yeah, the vulnerability lets the slightly trusted-but-still-untrustworthy shithead with an account run arbitrary commands through your n8n instance. That means they can basically treat your infrastructure like their personal playground — drop files, mess around, maybe mine some crypto if they’re feeling nostalgic. It’s practically a “help yourself to root” buffet. What could possibly go wrong?

The maintainers have scrambled out a patch, so stop sipping coffee and update your damn systems right now. Apparently, the issue affects setups where n8n is exposed to users with any kind of authentication access (which, let’s face it, is most of you muppets running this thing on your production servers without reading the manual). Good luck finding where your boss hid the update instructions.

Another week, another “oh look, remote code execution for breakfast” disclosure. At this rate, I’m thinking of converting all these CVE reports into a drinking game — except I’d be unconscious by Wednesday.

Read the original clusterbomb here.

Reminds me of the time some bright intern decided to run a “temporary” test script on the production automation server. Took down half the workflow jobs and fried a week’s worth of logs. When asked why, he said, “I didn’t think it’d actually run.” Yeah, neither did your career, sunshine.
