CVE-2025-31914 is a critical SQL Injection vulnerability (CWE-89) identified in the kamleshyadav Pixel WordPress Form BuilderPlugin & Autoresponder, affecting versions up to 1.0.2. This vulnerability arises from improper neutralization of special elements in SQL commands, allowing an attacker to perform Blind SQL Injection attacks. Blind SQL Injection means that although the attacker cannot directly see the results of the injected queries, they can infer data by observing application behavior or response times. The vulnerability is remotely exploitable over the network without requiring authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The scope is changed (S:C), meaning exploitation can affect resources beyond the vulnerable component, and the impact on confidentiality is high (C:H), with no impact on integrity (I:N) and low impact on availability (A:L). This suggests attackers can extract sensitive data from the backend database but cannot modify data or significantly disrupt service. The plugin is a WordPress form builder and autoresponder, which typically handles user input and stores or processes form submissions, making it a prime target for injection attacks if inputs are not properly sanitized. No patches or known exploits in the wild are reported yet, but the high CVSS score (9.3) and critical severity highlight the urgent need for remediation. The vulnerability was reserved in April 2025 and published in May 2025, indicating recent discovery. Given the plugin's integration with WordPress, a widely used CMS, the attack surface is significant, especially for websites relying on this plugin for form handling and autoresponse functionality.

For European organizations, the impact of this vulnerability can be substantial. Many businesses, government agencies, and NGOs in Europe use WordPress for their websites and rely on plugins like Pixel WordPress Form Builder & Autoresponder for customer engagement and data collection. Exploitation could lead to unauthorized disclosure of sensitive information such as user data, credentials, or business-critical information stored in the backend database. This breach of confidentiality can result in regulatory non-compliance, especially under GDPR, leading to heavy fines and reputational damage. Although the vulnerability does not allow data modification or deletion, the exposure of confidential data alone can disrupt business operations and erode customer trust. Additionally, attackers could leverage extracted data for further attacks, including phishing or identity theft. The low impact on availability means service disruption is less likely, but the confidentiality breach alone is critical. Organizations with public-facing WordPress sites using this plugin are at risk, particularly those handling personal or financial data. The lack of known exploits currently provides a window for proactive mitigation before widespread exploitation occurs.

1. Immediate action should be to identify all instances of the Pixel WordPress Form Builder & Autoresponder plugin in use across organizational websites. 2. Since no official patch links are provided yet, organizations should monitor vendor announcements and security advisories closely for patches or updates. 3. In the interim, consider disabling or uninstalling the plugin if feasible, especially on high-value or sensitive sites. 4. Implement Web Application Firewall (WAF) rules specifically designed to detect and block SQL injection attempts targeting this plugin’s endpoints. Custom WAF signatures can be developed based on known attack patterns for Blind SQL Injection. 5. Conduct thorough input validation and sanitization on all form inputs, even if the plugin is used, to reduce injection risks. 6. Employ database user accounts with least privilege, restricting access to only necessary data and operations to limit potential data exposure. 7. Perform regular security audits and penetration testing focusing on WordPress plugins and form handling components. 8. Monitor logs for unusual database query patterns or anomalies in form submission behavior that could indicate exploitation attempts. 9. Educate web administrators and developers about the risks of SQL injection and safe coding practices. 10. Prepare an incident response plan to quickly address any detected exploitation attempts.
