CVE-2025-4665 - Contact Form Cfdb7 Plugin

CVE-2025-4665

Vulnerability CVE-2025-4665 PLUGIN contact-form-cfdb7 CRITICAL

WordPress plugin Contact Form CFDB7 versions up to and including 1.3.2 are affected by a pre-authentication SQL injection vulnerability that cascades into insecure deserialization (PHP Object Injection). The weakness arises due to insufficient validation of user input in plugin endpoints, allowing crafted input to influence backend queries in unexpected ways. Using specially crafted payloads, this can escalate into unsafe deserialization, enabling arbitrary object injection in PHP. Although the issue is remotely exploitable without authentication, it does require a crafted interaction with the affected endpoint in order to trigger successfully.

Potential Impact

Severity is CRITICAL (CVSS 9.6). Depending on deployment context, affected components may be exposed to unauthorized actions or data integrity risk.

Exploitability Assessment

Exploitability is assessed as High based on published exploit references, low-bar exploit prerequisites.

Primary risk drivers: published exploit references, 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

Prioritize remediation where affected components process customer data, admin sessions, or Internet-exposed workflows.
