Super Forms - Security Vulnerability (CVE-2026-17609)
CVE-2026-17609
The Super Forms – Drag & Drop Form Builder plugin for WordPress is vulnerable to Arbitrary Directory Deletion in all versions up to, and including, 6.3.316 via the submit_form function. This is due to insufficient validation of attacker-controlled JSON field declarations against the actual form schema, combined with a non-effective ABSPATH guard that dirname() trivially bypasses by stripping the trailing slash. This makes it possible for unauthenticated attackers to recursively delete arbitrary directories on the server, including the WordPress root directory. Exploitation requires that an administrator has enabled the 'Delete files from server after form submissions' setting, though this is a documented and commonly-enabled feature.

Potential Impact
Severity is CRITICAL (CVSS 9.1). 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 published exploit references, remote code execution potential, low-bar exploit prerequisites.
Primary risk drivers: published exploit references, 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.
