PHP security updates October 2026

Posted October 21st, 2026 in System Status. Tags: , , .

Today, the PHP developers released versions 8.5.12, 8.4.27, 8.3.36 and 8.2.35 in order to fix two critical vulnerabilities. We’ve upgraded these PHP versions on our servers as a result.

Although it’s always a good idea to use a recent version of PHP, we’ve also applied the security fixes to older PHP versions 5.6 through 8.1, even though they’re no longer supported by the PHP authors. All versions of PHP on our servers are protected against the vulnerabilities disclosed today.

Customers should not notice any other changes, but as always, don’t hesitate to contact us if you have any trouble.
