CYBERSECURITY: PHP Vulnerability: It’s Really, Really Bad. “This is a huge, huge issue because PHP is everywhere. A vast number of websites use a LAMP stack (Linux, Apache, MySQL, and PHP), and PHP is in all of them. This is worse than the log4j vulnerability (which was bad enough), since in a pinch you can live without logging for a while. Remove PHP from your web server, and just about everything breaks. In theory, you could still serve up static web pages, but I’m betting most sites have PHP involved in that task as well, and anything serving up dynamic content (database call, stock prices, etc.) on a LAMP setup is going to break.”

“Folks, this is a bad one. If you run any sort of website, you need to get this one updated ASAP.”
