The Threat Landscape is Evolving
Hackers rarely attack WordPress core directly anymore. Instead, they exploit vulnerabilities in third-party plugins and themes. In recent weeks, several critical vulnerabilities have been discovered in widely used plugins that could allow attackers to take full control of affected websites.
Recent Critical Vulnerabilities (August 2026)
1. Unauthenticated Privilege Escalation in Popular Page Builder
A critical flaw (CVSS 9.8) was recently patched in a major page builder plugin with over 2 million active installs. The vulnerability allowed unauthenticated attackers to register as administrators.
