CVE-2026-5364 - Drag And Drop File Upload For Contact Form 7 Plugin
CVE-2026-5364
The Drag and Drop File Upload for Contact Form 7 plugin for WordPress is vulnerable to arbitrary file upload in versions up to, and including, 1.1.3. This is due to the plugin extracting the file extension before sanitization occurs and allowing the file type parameter to be controlled by the attacker rather than being restricted to administrator-configured values, which when combined with the fact that validation occurs on the unsanitized extension while the file is saved with a sanitized extension, allows special characters like '$' to be stripped during the save process. This makes it possible for unauthenticated attackers to upload arbitrary PHP files and potentially achieve remote code execution, however, an .htaccess file and name randomization is in place which restricts real-world exploitability.

Potential Impact
Severity is HIGH (CVSS 8.1). 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 remote code execution potential, low-bar exploit prerequisites.
Primary risk drivers: 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 87/100 (High, Very High) with priority P2 Urgent. Prioritize remediation where affected components process customer data, admin sessions, or Internet-exposed workflows.
