The U.S. National Security Agency’s sent out an alarming warning on Wednesday that two critical holes had been found in PHP, with patches already issued by the PHP Foundation.
PHP is a server-side programming language so widely used for web applications that it powers roughly 70% of the websites on the internet; by some accounts, that’s more than 33 million sites. It is also used by popular content management systems like WordPress.
The NSA warned that these holes are so severe that if a website can’t be patched immediately, it should be pulled off the web until it can be. The holes allow attackers to infiltrate the server’s file system or a database that may be used by the web app.
Interestingly, these holes have been tucked away in all versions of PHP since version 5, which was released in 2004. Websites not running relatively current versions of PHP will have some updating work to do, as PHP 8.1 and older versions are no longer supported. The recommendation is to update the web server to the current version of PHP, which is 8.5.12.
