How to use this

Read it. Then patch.

An advisory is an action list, not a news recap.

  • Check the severity and the date

    Critical means update today. The date shows when the vendor published the fix, and when we last added a follow-up.

  • Match it to what you run

    Many business sites run PHP inside WordPress or a custom app. If you are not sure, ask. The app name is not the PHP version.

  • Patch, or take it offline

    A partial setting is not a fix for a critical flaw. If the update cannot ship today, take that system off the internet until it can.

  • Call us when EMPIST manages the server

    We confirm the version and apply the vendor package. Sites you host somewhere else still need their own check.

FAQ

About these advisories

What they are, and what managed clients should do.

01What is an EMPIST security advisory?
A short action note when a platform businesses rely on has a critical patch. It says who is affected and what to do today. The source is the vendor and, when they publish, agencies such as the NSA.
02How often do you publish advisories?
When something needs action this week. This is not a weekly blog. Older notes stay here so you can see what was patched.
03If we are an EMPIST client, do you patch this for us?
On servers we manage, call the service desk at (866) 442-3018 or open a ticket in EMPIST 360. We confirm the PHP version and apply the package. A site hosted somewhere else still needs a check with that host.
04Where do the facts come from?
The vendor’s advisory. For this PHP alert, that is php.net and the NSA statement from October 21, 2026.

Not sure what your sites run?
