Cursor AI: A Security Disaster, As If We Didn’t Know

Oh, joy. Another “AI-powered” tool riddled with more holes than a Swiss cheese factory. This time it’s Cursor, the code editor that apparently thinks letting users upload files and then blindly trusting them is a good idea. Seriously? Are these people even *trying* to secure anything?

The gist of this steaming pile of incompetence is that a vulnerability allows Remote Code Execution (RCE). How? By swapping out a legitimate MCP file – which, apparently, handles extensions and shit – with a malicious one after it’s been approved. Approved! Like some rubber-stamping idiot didn’t bother to actually *look* at what they were approving. It lets attackers run whatever the hell they want on your system.

They claim fixes are rolling out, but honestly? If you’re using this thing, just uninstall it now and go back to a real editor. Or learn to code without hand-holding, for fuck’s sake. The vulnerability exists in versions before 0.8.12, so update if you absolutely *must* use this garbage.

The researchers found it, reported it (thank god for someone doing their job), and now we’re all supposed to pretend this didn’t happen. It’s just… fantastic. Just what the world needs: more insecure AI crapware.

  I once had to clean up a system where someone installed a “smart” toaster that was running a full Linux distribution and had been compromised by a botnet. A toaster, people! This Cursor thing feels about as well-thought-out as that disaster. Don’t be an idiot.
