CVE-2025-67518 identifies a critical SQL Injection vulnerability in the Accordion Slider PRO plugin developed by LambertGroup, affecting all versions up to and including 1.2. The vulnerability arises from improper neutralization of special elements in SQL commands, enabling attackers to inject malicious SQL code. This is a blind SQL injection, meaning attackers can infer database information by observing application behavior without direct output of database errors. The vulnerability requires no authentication and no user interaction, making it remotely exploitable over the network. Exploitation can lead to unauthorized data access, modification, or deletion, and potentially full system compromise if the database is critical to the web application. The CVSS v3.1 base score is 9.8, reflecting high impact on confidentiality, integrity, and availability, with low attack complexity and no privileges required. Although no exploits are currently known in the wild, the severity and ease of exploitation make this a high-risk vulnerability. The plugin is commonly used in WordPress environments to create interactive accordion sliders, often on commercial and informational websites, increasing the attack surface. The lack of available patches at the time of publication necessitates immediate mitigation efforts to prevent exploitation.

For European organizations, this vulnerability poses a severe risk to data confidentiality, as attackers can extract sensitive information from backend databases. Integrity is compromised as attackers may alter or delete data, potentially disrupting business operations or corrupting critical information. Availability can also be affected if attackers execute commands that degrade or crash the database service. Organizations relying on the Accordion Slider PRO plugin for customer-facing websites or internal portals risk reputational damage, regulatory penalties under GDPR for data breaches, and operational downtime. Given the plugin’s integration in various sectors including e-commerce, media, and government websites, the impact could be widespread. The ease of exploitation without authentication increases the likelihood of automated attacks targeting vulnerable sites across Europe. This could lead to large-scale data breaches or defacements, undermining trust and causing financial losses.

1. Immediately identify and inventory all instances of Accordion Slider PRO plugin in use within the organization’s web infrastructure. 2. Monitor vendor communications closely for official patches or updates addressing CVE-2025-67518 and apply them promptly once available. 3. Deploy Web Application Firewalls (WAFs) with specific SQL Injection detection and blocking rules to mitigate exploitation attempts in the interim. 4. Implement strict input validation and sanitization on all user-supplied data interacting with the plugin or related components. 5. Conduct security audits and penetration testing focusing on SQL injection vectors to identify and remediate similar vulnerabilities. 6. Restrict database user permissions to the minimum necessary to limit the impact of a successful injection attack. 7. Maintain regular backups of databases and web content to enable rapid recovery in case of compromise. 8. Educate development and operations teams about secure coding practices and the risks of SQL injection vulnerabilities. 9. Consider temporarily disabling or replacing the vulnerable plugin if immediate patching is not feasible. 10. Monitor logs and network traffic for unusual activity indicative of exploitation attempts.
