Updating WordPress will not fix this week's PHP vulnerability.
That surprises a lot of people. The two flaws, nicknamed PHP2Shell, sit in PHP itself, the engine underneath WordPress, Drupal, Joomla and most of the web. Your plugins, your theme and your security plugin all run on top of it. The patch has to come from whoever runs your server.
Here is the one move that matters: ask your hosting company or IT provider to confirm in writing that the October 21 PHP fixes are applied and that PHP was restarted afterward. Hosts patched at very different speeds, and "managed" doesn't always mean "done."
Two things worth knowing. Attack attempts are in the millions, but no successful compromise had been confirmed as of today. And if you're on PHP 8.1 or older, no official fix is coming, so that site needs an upgrade plan.
