WP Duplicate - Security Vulnerability (CVE-2026-123751)
CVE-2026-123751
The WP Duplicate WordPress plugin through 1.1.11 does not properly verify a request authentication value and does not validate the path or type of uploaded files, making it possible for unauthenticated attackers to write arbitrary files to the server and achieve remote code execution. This vulnerability is being actively exploited in the wild.

Technical Summary
The WP Duplicate WordPress plugin through 1.1.11 does not properly verify a request authentication value and does not validate the path or type of uploaded files, making it possible for unauthenticated attackers to write arbitrary files to the server and achieve remote code execution. This vulnerability is being actively exploited in the wild.
Potential Impact
Severity is CRITICAL (CVSS 9.8). Depending on deployment context, affected components may be exposed to unauthorized actions or data integrity risk.
Exploitability Assessment
Exploitability is assessed as Very High based on active exploitation indicators, remote code execution potential, low-bar exploit prerequisites.
Primary risk drivers: active exploitation indicators, remote code execution potential, low-bar exploit prerequisites
Mitigation Recommendations
Validate affected product versions, prioritize patching, and monitor references for vendor remediation guidance. If immediate patching is not possible, apply compensating controls and limit exposure of vulnerable surfaces.
Detection & Monitoring
Track authentication anomalies, unexpected file writes, and suspicious plugin API activity around affected components.
Business Impact Lens
AI risk score 100/100 (Critical, Very High) with priority P1 Immediate. Prioritize remediation where affected components process customer data, admin sessions, or Internet-exposed workflows.
