WordPress Easy Form Builder Plugin <= 3.8.15 - SQL Injection Vulnerability

The SQL Injection vulnerability in Easy Form Builder allows an attacker to bypass security controls and directly interact with the underlying database. Due to the 'blind' nature of the injection, attackers must infer information through trial and error, making exploitation potentially time-consuming but still highly impactful. Successful exploitation could lead to the extraction of sensitive user data, including usernames, passwords, email addresses, and potentially even financial information if the plugin is used to collect such data. Lateral movement within the WordPress environment is possible if the attacker can leverage the injected SQL queries to gain access to other administrative functions or data stores. The blast radius extends to all users of the affected plugin, particularly those handling sensitive data.

Websites utilizing Easy Form Builder for collecting user data, especially those handling sensitive information like personal details or financial data, are at significant risk. Shared hosting environments where multiple websites share the same database are particularly vulnerable, as a compromise of one site could potentially lead to the compromise of others.

The primary mitigation for CVE-2025-54678 is to immediately upgrade Easy Form Builder to version 3.8.16 or later. If upgrading is not immediately feasible due to compatibility issues or breaking changes, consider implementing temporary workarounds. Web Application Firewalls (WAFs) configured with rules to detect and block SQL injection attempts targeting the Easy Form Builder plugin can provide an additional layer of defense. Carefully review and sanitize all user inputs to prevent malicious SQL code from being injected. Monitor WordPress logs for suspicious database queries that might indicate an ongoing attack. After upgrading, confirm the fix by attempting a SQL injection payload through the form and verifying that it is properly sanitized and does not return any database information.
