CVE-2025-30784 identifies a critical SQL Injection vulnerability in the WP Shuffle WP Subscription Forms WordPress plugin, specifically affecting versions up to 1.2.3. The vulnerability arises from improper neutralization of special characters in SQL commands, allowing attackers to manipulate backend database queries. This can enable unauthorized retrieval, modification, or deletion of sensitive data stored in the database. The flaw does not require authentication or user interaction, increasing its risk profile. Although no public exploits have been reported yet, the vulnerability is publicly disclosed and documented in the CVE database. The plugin is commonly used to manage subscription forms on WordPress sites, which are widely deployed globally. The absence of a CVSS score necessitates an expert severity assessment based on the potential impact and exploitability. SQL Injection vulnerabilities are among the most severe web application flaws due to their ability to compromise confidentiality, integrity, and availability of data. Attackers could leverage this vulnerability to escalate privileges, extract user credentials, or disrupt website functionality. The vulnerability was reserved and published in March 2025 by Patchstack, a known security entity specializing in WordPress plugin vulnerabilities. No official patches or mitigation links have been provided yet, emphasizing the need for immediate attention from site administrators.

The impact of CVE-2025-30784 is significant for organizations using the WP Subscription Forms plugin. Successful exploitation can lead to unauthorized access to sensitive customer data, including subscription details and potentially other user information stored in the database. Attackers could alter or delete data, undermining data integrity and availability of subscription services. This could result in reputational damage, regulatory non-compliance (especially under GDPR or similar data protection laws), and financial losses. Since WordPress powers a large portion of websites globally, and subscription forms are common for marketing and customer engagement, the scope of affected systems is broad. The vulnerability's ease of exploitation without authentication increases the risk of automated attacks and mass exploitation attempts. Organizations with high-traffic websites or those in regulated industries face elevated risks. Additionally, compromised sites could be used as launchpads for further attacks, including phishing or malware distribution.

To mitigate CVE-2025-30784, organizations should immediately monitor for updates or patches released by WP Shuffle and apply them as soon as available. In the absence of official patches, administrators should consider temporarily disabling the WP Subscription Forms plugin or replacing it with alternative, secure subscription form solutions. Implementing a Web Application Firewall (WAF) with SQL Injection detection and prevention rules can help block exploitation attempts. Restrict database user permissions to the minimum necessary to limit the impact of potential injection attacks. Conduct thorough input validation and sanitization on all form inputs, especially those handled by the plugin. Regularly audit and monitor database logs for suspicious queries or anomalies. Employ security plugins that provide real-time monitoring and alerting for WordPress vulnerabilities. Finally, maintain regular backups of website data to enable recovery in case of compromise.
