The vulnerability identified as CVE-2025-60082 affects the PDF for WPForms plugin developed by add-ons.org, specifically versions up to 6.3.1. It is a deserialization of untrusted data vulnerability that enables object injection attacks. Deserialization vulnerabilities occur when an application deserializes data from untrusted sources without proper validation or sanitization, allowing attackers to inject malicious objects. In this case, the plugin processes serialized data related to PDF generation for WPForms, and improper handling allows crafted payloads to execute arbitrary code or manipulate application logic. This can lead to remote code execution (RCE), privilege escalation, or data tampering. The vulnerability does not require prior authentication, increasing its risk profile. Although no public exploits are currently known, the nature of the vulnerability makes it a critical concern once weaponized. The plugin is widely used in WordPress environments for form data processing and PDF generation, making the attack surface significant. The lack of a CVSS score indicates the need for a severity assessment based on technical characteristics. The vulnerability was reserved in September 2025 and published in December 2025, indicating recent discovery and disclosure. The absence of patch links suggests that fixes may still be pending or in development, emphasizing the need for immediate attention from users of the affected plugin.

For European organizations, the impact of this vulnerability can be substantial. Many businesses and public sector entities in Europe utilize WordPress and WPForms for customer interaction, data collection, and document generation. Exploitation could lead to unauthorized remote code execution, allowing attackers to compromise web servers, steal sensitive data, or pivot within internal networks. This could result in data breaches, service disruptions, and reputational damage. Organizations in sectors such as finance, healthcare, government, and e-commerce are particularly at risk due to the sensitive nature of the data processed. Additionally, the vulnerability could be leveraged to deploy ransomware or other malware, amplifying operational and financial impacts. The lack of authentication requirement means attackers can exploit this vulnerability remotely without user credentials, increasing the likelihood of attacks. The broad use of WordPress in Europe, combined with the criticality of affected services, underscores the need for urgent mitigation to protect confidentiality, integrity, and availability of systems.

1. Monitor add-ons.org and WPForms official channels closely for security patches addressing CVE-2025-60082 and apply them immediately upon release. 2. Until patches are available, consider disabling the PDF for WPForms plugin or restricting its usage to trusted environments only. 3. Implement web application firewalls (WAFs) with custom rules to detect and block suspicious serialized data patterns indicative of deserialization attacks. 4. Conduct code audits and penetration testing focused on deserialization handling within the plugin and related components. 5. Employ strict input validation and sanitization for all data processed by the plugin, especially serialized objects. 6. Limit the privileges of the web server and WordPress user accounts to minimize the impact of potential exploitation. 7. Maintain comprehensive logging and monitoring to detect anomalous activities related to deserialization or plugin usage. 8. Educate developers and administrators about the risks of deserialization vulnerabilities and secure coding practices. 9. Consider isolating WordPress instances or using containerization to reduce lateral movement in case of compromise. 10. Review backup and incident response plans to ensure rapid recovery if exploitation occurs.
