Hackers Exploit Metro4Shell RCE Flaw in React Native CLI npm Package — and Everyone’s Losing Their Shit

Well, guess what, another bloody day, another dumpster fire in software land. This week’s special? Some genius found a Remote Code Execution (RCE) shitstorm hiding in Metro4Shell, a nasty flaw baked right into the React Native CLI npm package. Yeah, that’s right — the same bloody tool thousands of devs use to build shiny mobile apps. Turns out it was more like a welcome mat saying, “Come on in, hackers, take the bloody server!”

So, some clever cyber assholes have been exploiting this for months — running arbitrary code remotely, dropping payloads, and basically turning systems into their personal playgrounds. All because someone left a hole wide enough to fit a bus through. The attackers scanned npm installs faster than your average dev says “works on my machine.” Cue the predictable chaos: exposed systems, compromised CI/CD pipelines, and sysadmins screaming into the void.

GitHub and the security gods are all “patch your systems now!” like that ever happens in the real world. The devs pushed an update, v3.3.7 or some equally meaningless number, claiming it fixes everything. Sure, champ. Until the next oh-look-another-fucking-hole-in-npm moment rolls around in five minutes. Because who doesn’t love living on the bleeding edge — emphasis on the bleeding.

If you’re still using the vulnerable version, congrats, you’re basically giving hackers free root access with a bow on top. Update that crap or prepare for the mother of all support tickets. And don’t act surprised when you end up explaining to your boss why “Metro bundler” turned into “Metro bomb launcher.”

Reminds me of the time an intern “optimized” our deployment scripts by chmodding everything to 777. It worked great — right until some jerk in Russia replaced our splash screen with a dancing worm. Good times. Now if you’ll excuse me, I have to go swear at a log file for a few hours.
