Apache has released a fix for a critical flaw in the HTTP/2 module of Apache HTTP Server, according to Wordfence. The flaw can lead to remote code execution, which means an attacker could run their own code on the server. This is not a WordPress plugin problem. It sits in the web server software your host runs.
What happened
The issue is tracked as CVE-2026-119618. It affects mod_http2, the module Apache uses to serve HTTP/2 requests. HTTP/2 is a newer, faster way for browsers to talk to a web server.
Apache lists versions 2.4.55 through 2.4.70 as affected. It released version 2.4.71 with the fix on November 11, 2026. Standalone mod_h2 releases 2.0.8 through 2.0.42 are also affected.
Who is affected
Apache uses HTTP/1.1 by default. HTTP/2 has to be turned on in the server configuration. A server that does not offer HTTP/2 through the affected module is not exposed to this flaw.
Apache sits in front of WordPress. It handles the connection before a request reaches PHP or your site. If an attacker exploits the flaw, the code runs with the web server’s privileges. That could expose or change sites and data on the server.
Hosts sometimes backport fixes into older versions. So the version number alone may not tell you whether your server is patched.
What to do
- Check your host’s website or status page for an announcement about this flaw.
- If you find nothing, ask your host two questions. Does your Apache server accept HTTP/2? Has the fix been installed?
- If you manage your own server, update to Apache 2.4.71 or later.
There is nothing to update in your WordPress dashboard. Keep WordPress and your plugins current as usual, but this fix has to come from your host or server administrator.
