CVE-2025-68590 is a critical SQL Injection vulnerability identified in the CRM Perks Integration for Contact Form 7 HubSpot plugin, affecting all versions up to and including 1.4.2. This plugin integrates WordPress Contact Form 7 submissions with HubSpot CRM, facilitating lead and contact management. The vulnerability arises from improper neutralization of special elements in SQL commands, allowing an attacker to inject malicious SQL queries remotely without authentication or user interaction. Specifically, it enables Blind SQL Injection, where attackers can infer data from the database by sending crafted requests and analyzing responses, even if direct error messages are not returned. The CVSS 3.1 score of 9.8 reflects the vulnerability's network attack vector, low complexity, no privileges or user interaction required, and its impact on confidentiality, integrity, and availability. Exploiting this flaw could allow attackers to extract sensitive customer data, modify or delete records, or disrupt service availability. Although no exploits are currently known in the wild, the widespread use of Contact Form 7 and HubSpot integrations in marketing and sales workflows makes this a high-risk vulnerability. The lack of a patch link suggests that vendors or maintainers have yet to release an official fix, emphasizing the need for immediate mitigation steps.

For European organizations, the impact of CVE-2025-68590 could be severe. Many businesses rely on WordPress with Contact Form 7 and CRM Perks plugins to manage customer interactions and lead data, often integrating with HubSpot CRM for marketing automation. Exploitation could lead to unauthorized disclosure of personal data, violating GDPR and other data protection regulations, resulting in legal penalties and reputational damage. The integrity of CRM data could be compromised, affecting business operations, sales forecasting, and customer relationship management. Availability impacts could disrupt customer-facing forms and backend CRM synchronization, leading to loss of business continuity. Given the critical nature of the vulnerability and the ease of exploitation, attackers could leverage this flaw for data exfiltration, ransomware deployment, or lateral movement within corporate networks. The absence of known exploits currently provides a window for proactive defense, but the risk of imminent exploitation is high due to the vulnerability's severity and public disclosure.

European organizations should immediately audit their WordPress environments to identify installations of the CRM Perks Integration for Contact Form 7 HubSpot plugin. Until an official patch is released, implement strict input validation and sanitization on all form inputs, particularly those interacting with the plugin. Deploy Web Application Firewalls (WAFs) with custom rules to detect and block SQL Injection patterns targeting this plugin. Monitor web server and application logs for unusual query patterns or repeated failed requests indicative of blind SQL injection attempts. Restrict network access to administrative interfaces and limit plugin usage to trusted users. Consider temporarily disabling the plugin if it is not critical to business operations. Engage with the plugin vendor for updates and subscribe to vulnerability advisories for timely patch deployment. Additionally, conduct regular backups of CRM and website data to enable recovery in case of compromise. Implementing Content Security Policy (CSP) and least privilege principles on database accounts used by the plugin can further reduce exploitation impact.
