CVE-2024-37235 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Groundhogg plugin for WordPress, developed by Adrian Tobey, affecting all versions up to 3.4.2.3. CSRF vulnerabilities allow attackers to induce authenticated users to perform unwanted actions on a web application without their knowledge. In this case, an attacker could craft a malicious web request that, when visited by a logged-in user of Groundhogg, executes unauthorized commands within the plugin's context. Groundhogg is widely used for marketing automation and customer relationship management on WordPress sites, managing sensitive customer data and marketing workflows. The vulnerability arises because Groundhogg fails to properly validate the origin of requests or implement anti-CSRF tokens, allowing state-changing requests to be executed without user consent. No authentication bypass is involved; however, the victim must be authenticated and visit a malicious page. There are no known public exploits at this time, and no CVSS score has been assigned. The vulnerability was reserved in June 2024 and published in January 2025. The lack of a patch link suggests that a fix may be pending or not yet publicly available. This vulnerability could be leveraged to manipulate marketing data, alter configurations, or disrupt service availability, impacting the integrity and availability of affected systems.

Organizations using Groundhogg for marketing automation and CRM on WordPress sites face risks including unauthorized changes to marketing campaigns, customer data manipulation, and potential service disruptions. Attackers exploiting this CSRF vulnerability could perform actions such as modifying contact lists, changing campaign parameters, or triggering unintended workflows, leading to data integrity issues and operational disruptions. The confidentiality impact is moderate since the attack does not directly expose data but could indirectly lead to data leakage if workflows are manipulated. The integrity impact is high due to unauthorized modification potential. Availability could also be affected if critical workflows or configurations are disrupted. The ease of exploitation is relatively high because it only requires the victim to be authenticated and visit a malicious site, with no additional authentication bypass or complex attack vectors needed. This could result in reputational damage, loss of customer trust, and financial consequences for organizations relying on Groundhogg for customer engagement.

Organizations should monitor for official patches or updates from Adrian Tobey and apply them promptly once available. In the interim, implement web application firewall (WAF) rules to detect and block suspicious cross-site requests targeting Groundhogg endpoints. Enforce strict same-site cookie policies to reduce CSRF risks. Review and harden user roles and permissions within WordPress to limit the number of users with administrative access to Groundhogg. Educate users to avoid clicking on suspicious links while authenticated on sensitive platforms. Developers and administrators should verify that all state-changing requests in Groundhogg include anti-CSRF tokens and validate the origin of requests. Consider disabling or restricting Groundhogg features that are not essential to reduce the attack surface. Regularly audit logs for unusual activity that could indicate exploitation attempts. Finally, maintain a robust backup and recovery plan to restore data integrity if unauthorized changes occur.
