Critical vulnerabilities in WordPress plugins – August 2021


To ensure that your WordPress website is secure and stays that way, you need to have a security plugin.

One reason is that they report regularly on critical vulnerabilities of plugins you might use.

There are few available, although my preference goes to Wordfence.

Critical vulnerabilities in WordPress plugins – August 2021

The Wordfence Threat Intelligence team found sofar these vulnerabilities:

XSS Vulnerability in SEOPress

A WordPress plugin installed on over 100,000 sites.

This flaw made it possible for an attacker to inject arbitrary web scripts on a vulnerable site which would execute anytime a user accessed the “All Posts” page.

They reached out to the plugin developer on July 29, 2021. After receiving confirmation of an appropriate communication channel the next day on July 30, 2021, we provided the full disclosure details. The vendor quickly acknowledged the report and a patch was released on August 4, 2021 in version 5.0.4.

We strongly recommend updating immediately to the latest patched version of SEOPress, version 5.0.4, if you are currently using a vulnerable version of the plugin.
