Cursor AI: A Code Editor That Couldn’t Secure a Fucking Prompt

Oh, joy. Another “AI-powered” tool that’s about as secure as a screen door on a submarine. Apparently, this Cursor AI code editor had a vulnerability where some clever bastard could inject commands into prompts and basically tell the thing to do whatever they wanted. Remote Code Execution (RCE), people! RCE! Like we don’t have enough of *that* going around.

The problem? It didn’t properly sanitize user input, meaning a malicious actor could craft a prompt that would execute shell commands on the server. They fixed it – surprise, surprise – by adding some input validation and sanitization. Groundbreaking stuff, really. Took them long enough. The fix was released in versions 0.7.12 and later.

The article mentions they’ve been handing out bug bounties, which is nice I guess, but honestly, if you’re building an AI tool that requires *any* kind of user input, you should have thought about this shit from the start. It’s not rocket science; it’s basic fucking security.

So yeah, update your Cursor AI if you actually use it. And for the love of all that is holy, don’t trust anything with “AI” in the name unless you want to spend your life patching holes.

Speaking of prompt injection, I once had to deal with a user who tried to get our internal systems to generate a list of all employee salaries by feeding it a carefully crafted query disguised as a “helpful request.” The system *almost* bought it. Almost. It took me three cups of coffee and a healthy dose of cynicism to shut that down. Honestly, people will try anything. Anything at all.
