CVE-2025-68590 identifies a Blind SQL Injection vulnerability in the CRM Perks Integration for Contact Form 7 HubSpot plugin, specifically in versions up to and including 1.4.2. The vulnerability arises from improper neutralization of special characters used in SQL commands, allowing attackers to inject arbitrary SQL code into backend database queries. Blind SQL Injection means attackers cannot directly see query results but can infer data by observing application behavior or response timing. This type of injection can be exploited to extract sensitive data, modify or delete records, or escalate privileges within the database. The plugin integrates Contact Form 7, a popular WordPress form plugin, with HubSpot CRM, making it a critical component for organizations managing customer interactions and marketing data. The vulnerability does not require authentication, increasing its risk profile, and no user interaction is needed beyond submitting crafted input through the form. Currently, no public exploits are known, but the vulnerability is published and could be targeted once exploit code becomes available. The absence of a CVSS score necessitates an independent severity assessment. The vulnerability affects the confidentiality and integrity of data, with potential impacts on availability if database integrity is compromised. The scope includes all websites using the affected plugin versions, which are common in small to medium enterprises and marketing-focused organizations. The vulnerability was reserved and published in December 2025, indicating recent discovery and disclosure.

For European organizations, this vulnerability could lead to unauthorized access to sensitive customer data stored in HubSpot CRM databases, including personal identifiable information (PII), marketing data, and business intelligence. Compromise of this data can result in regulatory violations under GDPR, leading to significant fines and reputational damage. Attackers exploiting this flaw could manipulate or delete critical data, disrupting business operations and customer relationship management. The integration nature of the plugin means that the impact extends beyond the WordPress site to the connected CRM system, potentially affecting data integrity across platforms. Organizations relying heavily on HubSpot for marketing automation and customer engagement in Europe are at heightened risk. Additionally, the lack of authentication requirement means attackers can exploit the vulnerability remotely without credentials, increasing the attack surface. The potential for data exfiltration and manipulation poses a critical threat to confidentiality and integrity, while availability could be affected if database corruption occurs. The impact is amplified in sectors with strict data protection requirements such as finance, healthcare, and public services prevalent in Europe.

1. Immediately audit all WordPress sites using the CRM Perks Integration for Contact Form 7 HubSpot plugin to identify affected versions (<=1.4.2). 2. Apply vendor patches or updates as soon as they are released to remediate the vulnerability. 3. Until patches are available, implement Web Application Firewalls (WAF) with custom rules to detect and block SQL injection patterns targeting the plugin’s endpoints. 4. Employ strict input validation and sanitization on all form inputs, especially those integrated with the HubSpot CRM, to neutralize special characters and prevent injection. 5. Conduct regular security scans and penetration tests focusing on SQL injection vectors in the affected plugin. 6. Monitor logs for unusual database query patterns or repeated failed attempts indicative of blind SQL injection probing. 7. Limit database user privileges for the WordPress application to the minimum necessary to reduce potential damage from exploitation. 8. Educate development and security teams about the risks of SQL injection and secure coding practices for third-party integrations. 9. Consider temporarily disabling the plugin if immediate patching is not feasible and alternative solutions exist. 10. Maintain up-to-date backups of databases and website content to enable recovery in case of compromise.
