- Community Submitter Notes
- This technical reference guide details the vulnerability mechanics, emergency WAF mitigations, and forensic remediation protocols required to defend against "wp2shell" (CVE-2026-63030 and CVE-2026-60137) in WordPress Core. The analysis examines how unauthenticated threat actors chain REST API batch-route tracking confusion with author__not_in parameter SQL injections to achieve pre-authentication Remote Code Execution on stock WordPress 6.9.x and 7.0.x installations. It provides systems administrators and web hosting engineers with an actionable roadmap for applying core patches (WordPress 7.0.2 / 6.9.5), blocking path and query-string REST variants at the reverse proxy layer, and executing command-line file integrity audits to detect rogue PHP webshells. wp2shell, WordPress, CVE-2026-63030, CVE-2026-60137, RCE, Remote Code Execution, SQL Injection, REST API, WAF, Web Security, AppSec, Linux Forensics, CMS Security
