CVE-2025-54678 is a critical SQL Injection vulnerability (CWE-89) identified in the Easy Form Builder plugin developed by hassantafreshi. This vulnerability allows an unauthenticated remote attacker to perform Blind SQL Injection attacks against affected installations of Easy Form Builder up to version 3.8.15. The flaw arises from improper neutralization of special elements in SQL commands, meaning that user-supplied input is not correctly sanitized or parameterized before being incorporated into SQL queries. This enables attackers to inject malicious SQL code, which can be used to extract sensitive information from the backend database without direct visibility of query results (blind injection). The CVSS v3.1 base score is 9.3, reflecting a critical severity due to the vulnerability's network attack vector, lack of required privileges or user interaction, and the potential for complete confidentiality compromise with limited impact on integrity and availability. The vulnerability affects all versions up to 3.8.15, with no patch currently available as of the published date (August 14, 2025). No known exploits are reported in the wild yet, but the high severity score and ease of exploitation make it a significant risk for organizations using this plugin. Easy Form Builder is typically used to create and manage forms on websites, often integrated into content management systems or custom web applications. Exploitation could lead to unauthorized disclosure of sensitive data stored in the database, including user credentials, personal data, or business-critical information. Given the scope and nature of the vulnerability, attackers could leverage this flaw to conduct further attacks, including reconnaissance and lateral movement within the affected environment.

For European organizations, the impact of this vulnerability can be substantial, especially for those relying on Easy Form Builder for customer-facing or internal web forms. The unauthorized disclosure of sensitive data could lead to violations of the EU General Data Protection Regulation (GDPR), resulting in significant financial penalties and reputational damage. Confidentiality breaches could expose personal data of EU citizens, including names, contact details, and potentially financial information, depending on the form data collected. The vulnerability's ability to be exploited remotely without authentication increases the risk of widespread attacks, including automated scanning and exploitation attempts. Additionally, the compromise of backend databases could facilitate further attacks such as phishing, identity theft, or fraud. The limited impact on integrity and availability reduces the risk of data tampering or service disruption but does not eliminate the threat to data privacy and compliance obligations. Organizations in sectors such as finance, healthcare, e-commerce, and public services, which often handle sensitive personal or financial data, are particularly at risk. The lack of a patch at the time of disclosure necessitates immediate risk mitigation to prevent exploitation.

Given the absence of an official patch, European organizations should implement several specific mitigation strategies: 1) Immediately review and restrict access to web forms powered by Easy Form Builder, including implementing web application firewalls (WAFs) with custom rules to detect and block SQL injection payloads targeting known vulnerable parameters. 2) Employ input validation and sanitization at the application layer where possible, ensuring that all user inputs are strictly validated against expected formats and lengths before processing. 3) Monitor web server and database logs for unusual or suspicious query patterns indicative of SQL injection attempts, enabling early detection and response. 4) Consider temporarily disabling or replacing Easy Form Builder with alternative form solutions that are verified secure until a patch is released. 5) Conduct a thorough security audit of all web applications using Easy Form Builder to identify and isolate vulnerable instances. 6) Educate development and security teams about the risks of SQL injection and the importance of parameterized queries and prepared statements in preventing such vulnerabilities. 7) Prepare incident response plans specifically addressing potential data breaches resulting from this vulnerability to minimize impact if exploitation occurs. 8) Stay updated with vendor communications and security advisories to apply patches or updates as soon as they become available.
