CVE-2025-31640 is a high-severity SQL Injection vulnerability (CWE-89) found in the LambertGroup Magic Responsive Slider and Carousel WordPress plugin, affecting versions up to 1.4. This vulnerability arises from improper neutralization of special elements used in SQL commands, allowing an attacker with at least low privileges (PR:L) and no user interaction (UI:N) to inject malicious SQL queries remotely (AV:N). The vulnerability impacts confidentiality significantly (C:H), with limited impact on availability (A:L) and no impact on integrity (I:N). The scope is changed (S:C), indicating that exploitation could affect resources beyond the vulnerable component, potentially compromising the underlying database and exposing sensitive data. Although no known exploits are currently reported in the wild, the CVSS 3.1 score of 8.5 reflects the high risk posed by this vulnerability. The vulnerability affects a widely used WordPress plugin that manages sliders and carousels, components often embedded in websites to enhance user experience. Exploitation could allow attackers to extract sensitive information from the database, such as user credentials or other confidential data, without authentication or user interaction, making it a critical concern for website administrators. The absence of available patches at the time of reporting increases the urgency for mitigation and monitoring. Given the plugin's integration with WordPress, a popular CMS in Europe, the vulnerability presents a significant attack vector for threat actors targeting European organizations relying on this plugin for their web presence.

For European organizations, this vulnerability poses a substantial risk to the confidentiality of data hosted on websites using the Magic Responsive Slider and Carousel plugin. Many European businesses, governmental agencies, and institutions rely on WordPress for their web infrastructure, and the presence of this vulnerable plugin could lead to unauthorized data disclosure, potentially violating GDPR and other data protection regulations. The ability to exploit this vulnerability remotely without user interaction and with low privileges increases the likelihood of automated attacks and mass exploitation attempts. Data breaches resulting from this vulnerability could lead to reputational damage, financial penalties, and operational disruptions. Additionally, the changed scope (S:C) suggests that the impact could extend beyond the plugin itself, potentially affecting the entire website or backend database, which might include customer data, internal records, or other sensitive information. The lack of known exploits in the wild currently provides a window for proactive defense, but the high CVSS score indicates that attackers may develop exploits rapidly once the vulnerability becomes widely known.

European organizations should immediately audit their WordPress installations to identify the presence of the Magic Responsive Slider and Carousel plugin, particularly versions up to 1.4. Until an official patch is released, organizations should consider disabling or uninstalling the plugin to eliminate the attack surface. Implementing Web Application Firewalls (WAFs) with rules tailored to detect and block SQL injection attempts targeting this plugin can provide interim protection. Monitoring web server and application logs for unusual SQL query patterns or suspicious activity related to the plugin endpoints is critical for early detection. Organizations should also enforce the principle of least privilege on WordPress user accounts to limit the potential for exploitation by low-privilege users. Regular backups of website data and databases should be maintained to enable rapid recovery in case of compromise. Finally, organizations should subscribe to vulnerability intelligence feeds and vendor advisories to apply patches promptly once available.
