TechDefenders Consulting / PHP runtime

Is your PHP site affected?

Two critical PHP flaws can expose applications running on affected versions. Check the version your site discloses, then patch the live runtime.

Check a URLTECHDEFENDERS CONSULTING · READ-ONLY

Use a site you own or manage. The check sends ordinary GET requests and reads the PHP version in response headers. Nothing is exploited.

01 / The versions

Fixed releases.

These upstream PHP releases contain the fixes. A version below the threshold on a covered branch needs attention.

PHP 8.2
8.2.35Fixed release
PHP 8.3
8.3.36Fixed release
PHP 8.4
8.4.27Fixed release
PHP 8.5
8.5.12Fixed release

Checking current PHP releases…

Using a vendor package? OS and long-term-support vendors may backport the fixes without changing the version shown in headers. Confirm that your exact package includes fixes for both CVEs. PHP 8.1 and older need migration to a supported branch.
02 / The response

Four steps to a safer runtime.

The application can be fully updated while its PHP runtime remains exposed. Focus on the version actually serving traffic.

01

Upgrade PHP

Install a fixed upstream release or a vendor package with fixes for both vulnerabilities.

02

Restart workers

Restart PHP-FPM, Apache, LiteSpeed, containers, and any other PHP workers so the patched runtime is loaded.

03

Verify the live site

Check the PHP version used by production web requests. A CLI version alone does not prove your web stack is patched.

04

Restrict access if needed

If patching is delayed, limit public exposure until your hosting team can deploy the fix.

Why it matters

The runtime sits beneath your app.

WordPress, Laravel, Drupal, Magento and other PHP applications can be affected through a vulnerable PHP runtime, regardless of the application version. Updating the app alone does not patch PHP.

How this check works

Evidence from the response.

The agent reads version headers and PHP session-cookie presence, then compares any disclosed version with the fixed releases. A hidden version or vendor backport can change the answer. The supplied Nuclei template includes intrusive crash probes; this site does not run them. Confirm the installed and running PHP package on the host.
