The vulnerability identified as CVE-2025-60174 affects the CRM Perks WP Gravity Forms Constant Contact Plugin, specifically versions up to and including 1.1.2. It is a deserialization of untrusted data vulnerability that enables object injection attacks. Deserialization vulnerabilities occur when untrusted input is deserialized by an application, allowing attackers to manipulate serialized objects to execute arbitrary code or alter application behavior. In this case, the plugin improperly handles serialized data, permitting attackers to inject malicious objects remotely without authentication or user interaction. This can lead to remote code execution, data theft, or denial of service. The plugin integrates Gravity Forms with Constant Contact, a popular email marketing service, making it a common component in WordPress sites that manage customer relationships and marketing campaigns. The CVSS v3.1 score of 9.8 reflects the vulnerability's critical nature, with attack vector being network-based, no required privileges or user interaction, and high impacts on confidentiality, integrity, and availability. Although no exploits are currently known in the wild, the ease of exploitation and potential damage necessitate urgent attention. The vulnerability was publicly disclosed in December 2025, with the issue reserved in September 2025. No official patches or mitigation links were provided at the time of disclosure, increasing the urgency for organizations to apply vendor updates once available or implement alternative mitigations.

For European organizations, the impact of CVE-2025-60174 can be severe. Many businesses in Europe rely on WordPress for their websites and use Gravity Forms with Constant Contact integration for marketing automation and customer engagement. Exploitation could lead to unauthorized access to sensitive customer data, including personal and marketing information, violating GDPR and other privacy regulations. Attackers could execute arbitrary code on web servers, leading to website defacement, data breaches, or pivoting to internal networks. This could disrupt business operations, damage brand reputation, and result in regulatory fines. The vulnerability's remote and unauthenticated nature increases the risk of widespread exploitation, especially for SMEs that may lack robust security monitoring. Additionally, the integration with Constant Contact means attackers might manipulate marketing campaigns or inject malicious content into communications, further amplifying reputational damage. The lack of known exploits currently offers a window for proactive defense, but the critical severity demands immediate action to prevent potential attacks.

1. Immediately update the WP Gravity Forms Constant Contact Plugin to the latest version once the vendor releases a patch addressing CVE-2025-60174. 2. Until a patch is available, disable or remove the plugin if it is not essential to reduce attack surface. 3. Deploy Web Application Firewalls (WAFs) with rules specifically targeting deserialization attacks and known exploit patterns related to Gravity Forms endpoints. 4. Implement strict input validation and sanitization at the application level to prevent malicious serialized data from being processed. 5. Monitor web server logs and application behavior for unusual requests or anomalies related to Gravity Forms submissions. 6. Restrict access to WordPress admin and plugin endpoints using IP whitelisting or VPNs where feasible. 7. Conduct regular security audits and penetration testing focusing on deserialization vulnerabilities. 8. Educate development and IT teams about the risks of deserialization and secure coding practices to prevent similar issues in custom plugins or integrations.
