CVE-2025-14074 is a vulnerability classified under CWE-862 (Missing Authorization) affecting the 'PDF for Contact Form 7 + Drag and Drop Template Builder' WordPress plugin developed by addonsorg. The issue stems from the absence of a capability check in the 'rednumber_duplicate' function, which is responsible for duplicating posts within the plugin's functionality. This missing authorization allows any authenticated user with at least Subscriber-level privileges to duplicate arbitrary posts, including those marked as private or password-protected. Since WordPress Subscriber roles are typically assigned to users with minimal permissions, this vulnerability significantly lowers the barrier for exploitation. The duplication process does not require user interaction beyond authentication, and the attack vector is network accessible (remote). The CVSS v3.1 score is 5.3 (medium), reflecting the limited impact on integrity and availability but a moderate confidentiality risk due to unauthorized duplication of sensitive content. The vulnerability affects all plugin versions up to 6.3.3, with no patches currently available and no known exploits in the wild. This flaw could be leveraged by attackers to exfiltrate sensitive information or create unauthorized copies of content, potentially leading to data leakage or privacy violations. The vulnerability does not allow modification or deletion of posts, nor does it cause denial of service, but the confidentiality breach risk is notable given the exposure of private or password-protected posts.

The primary impact of CVE-2025-14074 is unauthorized disclosure of sensitive content through duplication of posts that should be restricted, including private and password-protected posts. Organizations using the affected plugin may face confidentiality breaches if attackers with Subscriber-level access exploit this vulnerability to copy sensitive data. This can lead to exposure of proprietary information, customer data, or internal communications. While the vulnerability does not affect data integrity or availability, the unauthorized duplication could facilitate further attacks such as social engineering or phishing by exposing internal content. The ease of exploitation—requiring only authenticated Subscriber-level access—means that compromised or malicious low-privilege accounts can be leveraged to exploit this flaw. This risk is particularly significant for organizations that allow user registrations or have multiple contributors with Subscriber roles. The absence of patches and known exploits in the wild suggests a window of exposure until a fix is released and applied. Overall, the vulnerability poses a moderate risk to confidentiality and privacy for affected WordPress sites worldwide.

1. Immediately restrict user registrations or limit Subscriber-level access to trusted users only to reduce the attack surface. 2. Monitor WordPress logs and plugin activity for unusual post duplication events, especially involving private or password-protected posts. 3. Implement strict access controls and review user roles to ensure minimal necessary privileges are assigned. 4. Disable or remove the 'PDF for Contact Form 7 + Drag and Drop Template Builder' plugin if it is not essential to reduce exposure. 5. Follow the vendor and WordPress plugin repository for updates and apply patches promptly once available. 6. Consider implementing Web Application Firewall (WAF) rules to detect and block suspicious requests targeting the duplication function. 7. Educate site administrators and users about the risks of unauthorized content duplication and encourage strong authentication practices. 8. Conduct regular security audits of WordPress plugins and configurations to identify and remediate similar authorization issues proactively.
