Executive Summary
In July 2026, two critical vulnerabilities in WordPress Core, identified as CVE-2026-60137 and CVE-2026-63030, were disclosed. When exploited together, these flaws, collectively termed 'WP2Shell,' allow unauthenticated remote code execution on default WordPress installations. CVE-2026-60137 is an SQL injection vulnerability in the 'author__not_in' parameter of WP_Query, while CVE-2026-63030 is a REST API batch-route confusion issue. Attackers have rapidly developed and disseminated proof-of-concept exploits, leading to widespread exploitation attempts against millions of WordPress sites worldwide. Organizations are urged to update to the latest WordPress versions immediately to mitigate this threat. (vulncheck.com)
The rapid exploitation of WP2Shell underscores the increasing sophistication and speed of threat actors in leveraging newly disclosed vulnerabilities. This incident highlights the critical importance of timely patching and proactive security measures to protect web assets from emerging threats.
Why This Matters Now
The WP2Shell vulnerabilities are actively being exploited in the wild, posing an immediate risk to millions of WordPress sites. Organizations must prioritize patching to prevent potential data breaches and service disruptions.
Attack Path Analysis
Attackers exploited the WP2Shell vulnerability chain to gain unauthenticated remote code execution on WordPress sites. They escalated privileges by creating new administrator accounts. Subsequently, they moved laterally within the compromised environment to access additional resources. Attackers established command and control channels to maintain persistent access. They exfiltrated sensitive data from the compromised servers. Finally, they deployed malicious plugins to maintain access and potentially disrupt services.
