CVE-2025-69351 is a Blind SQL Injection vulnerability found in the Ninja Tables plugin developed by Shahjahan Jewel, affecting versions up to and including 5.2.4. The root cause is improper neutralization of special elements in SQL commands, which allows attackers to inject crafted SQL payloads that the backend database executes. Unlike classic SQL Injection, Blind SQL Injection does not return direct query results, making exploitation more complex but still feasible through inference techniques such as timing attacks or boolean-based responses. This vulnerability can be exploited remotely via web requests that interact with Ninja Tables functionality, typically without requiring authentication, increasing the attack surface. Successful exploitation can lead to unauthorized access to sensitive data stored in the database, data modification, or denial of service by corrupting or deleting data. The vulnerability is currently published with no CVSS score and no known public exploits, indicating it is newly disclosed and unpatched. Ninja Tables is commonly used in WordPress environments to create and manage tables, often in e-commerce or data-driven websites, making it a valuable target for attackers seeking to compromise web applications. The lack of available patches or mitigations at the time of disclosure necessitates immediate attention from users of the affected versions.

For European organizations, the impact of CVE-2025-69351 can be significant, particularly for those relying on Ninja Tables within WordPress sites that handle personal data, financial information, or other regulated data categories under GDPR. Exploitation could lead to data breaches exposing customer or employee information, resulting in regulatory fines, reputational damage, and operational disruption. Additionally, attackers could manipulate or delete critical data, impacting business continuity and trustworthiness of services. The vulnerability's ability to be exploited without authentication broadens the threat landscape, potentially allowing external attackers to compromise systems without insider access. Organizations in sectors such as e-commerce, finance, healthcare, and government are particularly at risk due to the sensitive nature of their data and the common use of WordPress-based solutions. The absence of known exploits currently reduces immediate risk but also means organizations must proactively prepare defenses before attackers develop reliable exploit techniques.

To mitigate CVE-2025-69351, organizations should first monitor official Shahjahan Jewel and Ninja Tables channels for patch releases and apply updates immediately upon availability. In the interim, implement strict input validation and sanitization on all user-supplied data interacting with Ninja Tables, employing allowlists where possible. Employ parameterized queries or prepared statements in any custom code interfacing with Ninja Tables to prevent injection. Restrict database user permissions to the minimum necessary, avoiding high-privilege accounts for web applications. Enable Web Application Firewalls (WAFs) with rules targeting SQL Injection patterns, including blind injection techniques, to detect and block suspicious requests. Conduct thorough security audits of WordPress environments, including plugin inventories and configurations, to identify and isolate vulnerable instances. Educate development and operations teams on secure coding practices and the risks of SQL Injection. Finally, implement comprehensive logging and monitoring to detect anomalous database queries or web requests indicative of exploitation attempts.
