## What it looks like

The host runs a PHP version without the fixes available in supported releases.

## Why it matters

A server-side flaw may remain exploitable despite updated WordPress code.

## What to check

Check the PHP version in Site Health and plan a supported upgrade.

## Documentation

This is an exploit pattern to check in installed components, not a claim that every WordPress site has this flaw. Confirm the product and version against its advisories before treating a site as affected. See [WordPress hardening guide](https://developer.wordpress.org/advanced-administration/security/hardening/).
