Dropping security updates for WordPress versions 4.1 through 4.6

As of July 2025 the WordPress Security Team no longer provides security updates for WordPress versions 4.1 through 4.6. These branches are nine or more years old and over 99% of WordPress installations run newer versions, so exposure is limited — but any site still on 4.1–4.6 is now permanently unpatched and should upgrade as soon as possible.

4.1

Lo que esto significa bajo una licencia de SharedLicense

Sites on WordPress 4.1–4.6 accumulate unpatched vulnerabilities from that point on; every flaw disclosed after July 2025 applies to them indefinitely.


As of July 2025, the WordPress Security Team will no longer provide security updates for WordPress versions 4.1 through 4.6.

These versions were first released nine or more years ago and over 99% of WordPress installations run a more recent version. The chances this will affect your site, or sites, is very small.

If you are unsure if you are running an up-to-date version of WordPress, please log in to your site’s dashboard. Out of date versions will display a notice that looks like this:

Dashboard notice: "WordPress 6.8.1 is available! Please update now."

The version you are running is displayed in the bottom of the “At a Glance” section of the dashboard.

As a reminder, the only actively supported version of WordPress is the most recent one. Security updates are only backported to older branches as a courtesy.

The Make WordPress Security blog has further details about the process to end support.

Preguntas frecuentes

Which WordPress versions lost security updates?
Versions 4.1 through 4.6 — the WordPress Security Team stopped back-porting security fixes to them as of July 2025.
How do I check my WordPress version?
Log in to the site dashboard and look at the At a Glance panel — the running version is displayed there. Out-of-date versions also show an update notice.
Which WordPress versions are still supported?
Only the most recent version of WordPress receives active security support (currently the 7.x line with its security point releases). Sites on 4.7–6.x should also plan upgrades, as support for those branches narrows over time.
What should I do if my site runs WordPress 4.1–4.6?
Upgrade immediately — first back up the site and its database, then update to the latest WordPress, and test plugins and themes for compatibility. An unpatched 4.x site should never face the public internet.
