CVE-2025-60080 identifies a deserialization of untrusted data vulnerability in the 'PDF for Gravity Forms + Drag And Drop Template Builder' plugin developed by add-ons.org, affecting versions up to and including 6.3.0. Deserialization vulnerabilities occur when software deserializes data from untrusted sources without proper validation, enabling attackers to inject malicious objects. In this case, the plugin processes serialized data related to PDF generation from Gravity Forms submissions. An attacker could exploit this flaw by submitting crafted serialized payloads through form inputs or API endpoints, leading to object injection. This can result in remote code execution, privilege escalation, or data manipulation within the affected WordPress environment. The vulnerability is particularly critical because Gravity Forms is widely used for form handling in WordPress sites, and the plugin integrates deeply with form data to generate PDFs dynamically. No CVSS score has been assigned yet, and no known exploits have been reported in the wild as of the publication date (December 18, 2025). However, the nature of deserialization vulnerabilities typically allows for relatively straightforward exploitation once the attack vector is identified. The vulnerability was reserved in late September 2025 and published in December 2025, indicating recent discovery. The lack of available patches at the time of reporting necessitates immediate attention to mitigation strategies.

For European organizations, the impact of this vulnerability can be significant, especially for those relying on WordPress sites with Gravity Forms and the affected PDF plugin for business-critical operations such as customer data collection, contract generation, or invoicing. Exploitation could lead to unauthorized code execution on web servers, resulting in data breaches, defacement, or further network compromise. Confidentiality is at risk due to potential data exposure; integrity can be compromised through manipulation of form data or generated documents; and availability may be affected if attackers disrupt services or deploy ransomware. Organizations in sectors like finance, healthcare, legal, and e-commerce, where form data is sensitive, are particularly vulnerable. The absence of known exploits provides a window for proactive defense, but the widespread use of WordPress and Gravity Forms in Europe increases the attack surface. Additionally, regulatory frameworks such as GDPR impose strict data protection requirements, making exploitation consequences more severe in terms of compliance and reputational damage.

1. Monitor add-ons.org and the plugin vendor for official patches addressing CVE-2025-60080 and apply them immediately upon release. 2. Until patches are available, restrict access to Gravity Forms submission endpoints using web application firewalls (WAFs) or IP whitelisting to limit exposure to untrusted users. 3. Implement strict input validation and sanitization on all form inputs to prevent malicious serialized payloads from being processed. 4. Disable or limit the use of serialized data handling features within the plugin if configurable. 5. Conduct thorough logging and monitoring of form submissions and server behavior to detect anomalous activities indicative of exploitation attempts. 6. Consider isolating the WordPress environment hosting the plugin using containerization or network segmentation to reduce lateral movement risk. 7. Educate development and security teams about the risks of deserialization vulnerabilities and secure coding practices. 8. Regularly audit installed plugins and remove unnecessary or outdated components to minimize attack vectors.
