A critical PHP vulnerability may take websites down today

A critical PHP remote-code-execution vulnerability with a 9.2 severity score could affect a very large share of internet-facing websites and web apps, including WordPress-based environments, creating immediate risk of outages, data theft, and arbitrary code execution. For CIOs and technology leaders, this is a time-sensitive operational and governance issue: patching must be handled manually, ownership for PHP updates needs to be clear, and organizations may need to temporarily isolate or take affected services offline until remediation is complete.
