The Reactflow Visitor Recording and Heatmaps plugin for WordPress suffers from a Cross-Site Request Forgery (CSRF) vulnerability identified as CVE-2024-11975. This vulnerability exists due to missing or incorrect validation of the _wpnonce parameter, which is intended to protect against unauthorized requests by verifying the legitimacy of user actions. Without proper nonce validation, attackers can craft malicious web requests that, when executed by an authenticated administrator (e.g., by clicking a specially crafted link), cause the site to perform unintended actions. This can lead to unauthorized changes or injection of malicious scripts, compromising the confidentiality and integrity of the affected WordPress site. The vulnerability affects all versions up to and including 1.0.10 of the plugin. The CVSS 3.1 base score is 6.1, reflecting a medium severity level, with an attack vector of network (remote), low attack complexity, no privileges required, but user interaction needed. The scope is changed, indicating that the vulnerability can affect resources beyond the initially vulnerable component. No public exploits have been reported yet, but the risk remains significant due to the widespread use of WordPress and the plugin. The vulnerability highlights the importance of nonce validation in WordPress plugins to prevent CSRF attacks.

This vulnerability can allow attackers to perform unauthorized actions on WordPress sites using the Reactflow Visitor Recording and Heatmaps plugin by tricking site administrators into clicking malicious links. The impact includes potential unauthorized changes to site settings, injection of malicious scripts, or manipulation of visitor data, which can compromise site confidentiality and integrity. While availability is not directly affected, the unauthorized actions could lead to reputational damage, data breaches, or further exploitation. Organizations relying on this plugin risk exposure to targeted attacks, especially if administrators are not trained to recognize phishing attempts or malicious links. The vulnerability's exploitation does not require authentication but does require user interaction, which may limit automated exploitation but still poses a significant risk in social engineering scenarios.

To mitigate this vulnerability, organizations should immediately update the Reactflow Visitor Recording and Heatmaps plugin to a version that includes proper nonce validation once available. Until a patch is released, administrators should implement manual nonce checks in the plugin code to validate the _wpnonce parameter on all sensitive actions. Additionally, site administrators should be trained to avoid clicking on suspicious links and employ web security measures such as Content Security Policy (CSP) to limit script execution. Employing multi-factor authentication (MFA) for WordPress admin accounts can reduce the risk of unauthorized access. Monitoring and logging administrative actions can help detect suspicious activities. Finally, restricting administrative access by IP or using a Web Application Firewall (WAF) with CSRF protections can further reduce exposure.
