CVE-2025-14074 in PDF for Contact Form 7 & Drag and Drop Template Builder Plugin
Summary
by MITRE • 12/12/2025
The PDF for Contact Form 7 + Drag and Drop Template Builder plugin for WordPress is vulnerable to unauthorized post duplication due to a missing capability check on the 'rednumber_duplicate' function in all versions up to, and including, 6.3.3. This makes it possible for authenticated attackers, with Subscriber-level access and above, to duplicate arbitrary posts, including password protected or private ones.

The vulnerability identified as CVE-2025-14074 affects the PDF for Contact Form 7 + Drag and Drop Template Builder plugin for WordPress, specifically targeting versions up to and including 6.3.3. This security flaw represents a critical authorization bypass issue that undermines the integrity of WordPress content management systems. The vulnerability stems from an insufficient capability check within the plugin's codebase, creating a pathway for malicious actors to exploit the system's permission controls. The affected plugin serves as a bridge between contact form functionality and template building capabilities, making it a potential vector for widespread content manipulation across WordPress installations.
The technical implementation of this vulnerability resides in the 'rednumber_duplicate' function which lacks proper authorization validation before executing post duplication operations. This function operates without verifying whether the authenticated user possesses sufficient privileges to duplicate the target content, effectively allowing any user with Subscriber-level access or higher to perform unauthorized duplication activities. The flaw manifests as a missing capability check that should validate user permissions against the specific action being requested. According to CWE-863, this represents a weakness in authorization checks where the system fails to properly verify that an actor has sufficient privileges to perform a requested operation, directly correlating to the privilege escalation vulnerability present in this WordPress plugin.
The operational impact of this vulnerability extends beyond simple content duplication, as it enables attackers to replicate sensitive or restricted posts including those protected by passwords or marked as private. This capability allows malicious users to potentially access and duplicate confidential information that should remain restricted to authorized personnel only. The vulnerability affects the core WordPress post management system by bypassing the standard permission models that govern content access and modification. Attackers can leverage this flaw to create multiple copies of protected content, potentially leading to information disclosure, content manipulation, or even the creation of unauthorized duplicate pages that could be used for malicious purposes such as phishing or spam distribution.
From a cybersecurity perspective, this vulnerability aligns with ATT&CK technique T1078.004 which covers legitimate credentials, specifically focusing on the abuse of valid accounts to perform unauthorized actions. The vulnerability essentially allows attackers to use their legitimate subscriber accounts to perform actions that should be restricted to higher privilege levels. Organizations running affected WordPress installations face significant risks including unauthorized content modification, potential data leakage through duplicated private posts, and possible reputational damage from malicious content distribution. The impact is particularly severe because the vulnerability affects the fundamental content management capabilities of WordPress, making it a prime target for exploitation in broader attack campaigns.
The recommended mitigation strategy involves immediate upgrading of the affected plugin to version 6.3.4 or later, which contains the necessary capability checks to prevent unauthorized post duplication. Administrators should also conduct thorough audits of user roles and permissions to ensure that only trusted users maintain Subscriber-level access or higher. Additionally, implementing network monitoring solutions can help detect unusual post duplication activities that might indicate exploitation attempts. Security teams should consider disabling the plugin temporarily if immediate updates are not feasible, while also reviewing other plugins for similar authorization bypass vulnerabilities through the WordPress plugin repository. The vulnerability highlights the critical importance of proper input validation and capability checks in web applications, particularly those handling user-generated content or sensitive data within content management systems.
