The CVE-2025-60089 vulnerability affects the CRM Perks WP Gravity Forms FreshDesk Plugin, specifically versions up to and including 1.3.5. The vulnerability is a deserialization of untrusted data issue, which allows an attacker to inject malicious objects into the deserialization process. Deserialization vulnerabilities occur when applications deserialize data from untrusted sources without proper validation, enabling attackers to manipulate the serialized data to execute arbitrary code, escalate privileges, or cause denial of service. In this case, the plugin processes serialized data related to FreshDesk integration within WordPress Gravity Forms, a popular form-building plugin. The flaw can be exploited remotely without authentication, as the plugin accepts input that can be crafted maliciously. Although no public exploits are currently documented, the vulnerability is critical because object injection can lead to remote code execution, data compromise, or system takeover. The plugin is widely used by organizations that integrate customer support workflows via FreshDesk into their WordPress sites, making it a valuable target for attackers. The vulnerability was reserved in September 2025 and published in December 2025, but no patch or CVSS score has been released yet. The lack of a patch increases the urgency for organizations to implement interim mitigations.

For European organizations, this vulnerability poses a significant risk to the confidentiality, integrity, and availability of their web infrastructure. Exploitation could allow attackers to execute arbitrary code on web servers hosting the vulnerable plugin, potentially leading to full system compromise, data theft, or disruption of customer support services. Organizations relying on FreshDesk integrations for customer relationship management and support ticketing may experience operational downtime and reputational damage. Given the widespread use of WordPress and FreshDesk in Europe, especially among SMEs and enterprises in sectors like retail, finance, and public services, the impact could be broad. Additionally, GDPR compliance may be jeopardized if personal data is exposed or systems are compromised. The vulnerability's ease of exploitation without authentication increases the likelihood of attacks, including automated scanning and exploitation attempts by cybercriminals or state-sponsored actors targeting European digital infrastructure.

Until an official patch is released, European organizations should implement the following specific mitigations: 1) Restrict access to endpoints handling serialized data by implementing web application firewall (WAF) rules to detect and block suspicious serialized payloads or object injection patterns. 2) Disable or limit the use of the WP Gravity Forms FreshDesk Plugin if feasible, especially on publicly accessible forms that accept user input. 3) Employ strict input validation and sanitization on all data processed by the plugin, particularly serialized data inputs, to prevent malicious object injection. 4) Monitor logs for unusual deserialization activity or errors indicative of exploitation attempts. 5) Isolate WordPress environments using this plugin in segmented network zones to limit lateral movement in case of compromise. 6) Prepare for rapid patch deployment by subscribing to vendor advisories and testing updates in staging environments. 7) Consider deploying runtime application self-protection (RASP) tools that can detect and block deserialization attacks in real time. These measures go beyond generic advice by focusing on the specific attack vector and plugin context.
