CVE-2024-7389 is a vulnerability identified in the Forminator plugin for WordPress, specifically affecting all versions up to and including 1.29.1. The issue arises from insufficient protection of sensitive credentials, classified under CWE-522, within the plugin's HubSpot integration component (class-forminator-addon-hubspot-wp-api.php). This flaw allows unauthenticated remote attackers to extract the developer API key used for HubSpot integration. With access to this key, attackers can manipulate the plugin's integration with HubSpot, potentially altering configurations or extracting personally identifiable information (PII) of users interacting with the plugin forms. The vulnerability is exploitable over the network without any authentication or user interaction, making it highly accessible to attackers. The CVSS v3.1 base score is 7.5, reflecting a high severity primarily due to the impact on confidentiality and ease of exploitation. No known public exploits have been reported yet, but the exposure of API keys represents a critical risk vector for data leakage and unauthorized system manipulation. The vulnerability affects a widely used WordPress plugin that provides contact, payment, and custom form building capabilities, often integrated with HubSpot for marketing and CRM purposes.

The primary impact of CVE-2024-7389 is the compromise of confidentiality through unauthorized disclosure of the HubSpot developer API key. This can lead to unauthorized access and manipulation of the HubSpot integration, potentially allowing attackers to extract sensitive user data, including personally identifiable information collected via forms. Organizations relying on this plugin for customer interactions and data collection risk data breaches, loss of customer trust, and regulatory non-compliance (e.g., GDPR, CCPA). Additionally, attackers could alter integration settings, causing disruption or misuse of marketing and CRM workflows. Since the vulnerability requires no authentication and can be exploited remotely, the attack surface is broad, affecting any WordPress site using the vulnerable plugin with HubSpot integration enabled. This could lead to widespread data exposure and operational impacts, especially for businesses heavily dependent on HubSpot for customer engagement and data management.

To mitigate CVE-2024-7389, organizations should immediately update the Forminator plugin to a version where this vulnerability is patched once available. Until a patch is released, administrators should consider disabling the HubSpot integration within the plugin to prevent exposure of the API key. Restricting access to the plugin files and endpoints, particularly class-forminator-addon-hubspot-wp-api.php, via web application firewalls (WAFs) or server-level access controls can reduce exposure. Monitoring and auditing API key usage within HubSpot for unusual activity is recommended to detect potential compromise. Additionally, rotating the HubSpot developer API key after patching or disabling the integration will invalidate any keys potentially exposed. Employing the principle of least privilege for API keys and ensuring that keys have limited scope and permissions can minimize damage if keys are leaked. Finally, organizations should review their WordPress security posture, including plugin management and vulnerability scanning, to prevent similar issues.
