CVE-2025-68534 identifies a missing authorization vulnerability in the PDF for WPForms plugin developed by add-ons.org, affecting all versions up to and including 6.3.0. This vulnerability arises from improperly configured access control security levels, allowing attackers to bypass authorization checks. The plugin is designed to generate PDFs from WPForms submissions within WordPress environments. Due to the missing authorization, an attacker could potentially perform unauthorized operations such as accessing, modifying, or exporting form data in PDF format without proper permissions. The vulnerability does not require user interaction, and exploitation could be performed remotely if the attacker can access the vulnerable endpoint. Although no exploits have been reported in the wild, the flaw presents a significant risk to the confidentiality and integrity of sensitive data collected via WPForms. The lack of a CVSS score indicates that the vulnerability is newly disclosed and not yet fully assessed, but the nature of missing authorization typically results in a high severity rating. The vulnerability affects a widely used WordPress plugin, increasing the potential attack surface across numerous websites globally. The issue was reserved in December 2025 and published in February 2026, with no patches currently linked, emphasizing the need for immediate attention from site administrators and developers.

The missing authorization vulnerability in PDF for WPForms can lead to unauthorized access and manipulation of form data, potentially exposing sensitive user information such as personal details, payment information, or confidential submissions. This can result in data breaches, loss of customer trust, and regulatory compliance violations (e.g., GDPR, CCPA). Attackers might exploit this flaw to generate unauthorized PDF exports of form data, leading to data leakage. Additionally, unauthorized modification of form data could disrupt business processes or enable further attacks such as phishing or fraud. The vulnerability affects any organization using the affected plugin, including e-commerce sites, service providers, and enterprises relying on WordPress for customer interactions. The ease of exploitation, combined with the widespread use of WPForms, amplifies the risk of large-scale impact. Although no known exploits exist yet, the vulnerability's presence in a critical plugin component makes it a high-risk issue that could be targeted by attackers once exploit code becomes available.

Until an official patch is released, organizations should implement strict access control measures at the WordPress and server levels to restrict access to the PDF for WPForms plugin endpoints. This includes limiting administrative and editor roles to trusted users only and employing web application firewalls (WAFs) to detect and block suspicious requests targeting the plugin. Monitoring logs for unusual access patterns related to PDF generation or form data exports can help identify attempted exploitation. Site administrators should disable or uninstall the PDF for WPForms add-on if it is not essential to reduce the attack surface. Additionally, applying the principle of least privilege to all WordPress users and regularly updating all plugins and themes can help mitigate risks. Once a patch is available, immediate application is critical. Organizations should also consider implementing multi-factor authentication (MFA) for WordPress admin accounts to prevent unauthorized access that could facilitate exploitation.
