The CVE-2025-60089 vulnerability is a critical security flaw found in the CRM Perks WP Gravity Forms FreshDesk Plugin, specifically affecting versions up to and including 1.3.5. The vulnerability arises from insecure deserialization of untrusted data, which allows attackers to perform object injection attacks. Object injection can enable attackers to manipulate application logic, execute arbitrary code, or escalate privileges by injecting malicious serialized objects into the plugin's deserialization process. This vulnerability is remotely exploitable over the network without requiring authentication or user interaction, making it highly accessible to attackers. The CVSS v3.1 score of 9.8 reflects the critical nature of this vulnerability, with high impact on confidentiality, integrity, and availability of affected systems. The plugin integrates FreshDesk ticketing functionality with WordPress Gravity Forms, commonly used for customer support and form management. Exploitation could lead to full compromise of the WordPress environment, data leakage, defacement, or service disruption. No patches or known exploits are currently publicly available, but the vulnerability was reserved and published in late 2025, indicating recent discovery. The lack of patch links suggests that immediate mitigation steps are necessary until an official fix is released.

For European organizations, this vulnerability poses a severe risk, especially for those relying on WordPress sites integrated with FreshDesk via the CRM Perks plugin. Successful exploitation could lead to unauthorized access to sensitive customer data, disruption of customer support services, and potential lateral movement within corporate networks. This could result in data breaches violating GDPR regulations, leading to significant financial penalties and reputational damage. The critical severity and ease of exploitation mean attackers could rapidly compromise multiple sites, affecting business continuity and customer trust. Organizations in sectors such as finance, healthcare, and e-commerce, which often use FreshDesk for customer interactions, are particularly vulnerable. Additionally, the potential for full system compromise could enable attackers to deploy ransomware or other malware, amplifying the impact. The lack of authentication and user interaction requirements further increases the threat level, making automated mass exploitation feasible.

1. Immediately monitor vendor communications and security advisories for an official patch or update to the CRM Perks WP Gravity Forms FreshDesk Plugin and apply it as soon as it becomes available. 2. Until patched, restrict access to the plugin’s endpoints by implementing IP whitelisting or VPN-only access for administrative and form submission interfaces. 3. Deploy a Web Application Firewall (WAF) with custom rules to detect and block suspicious serialized object payloads and known deserialization attack patterns targeting WordPress plugins. 4. Conduct thorough logging and monitoring of web server and application logs for anomalous requests that may indicate exploitation attempts. 5. Review and harden WordPress security configurations, including disabling unnecessary plugins and limiting plugin permissions. 6. Educate IT and security teams about the risks of deserialization vulnerabilities and ensure incident response plans include steps for this type of attack. 7. Consider isolating critical WordPress instances or running them in containerized environments to limit potential lateral movement. 8. Perform regular backups of WordPress sites and databases to enable rapid recovery in case of compromise.
