CVE-2025-12483 is an SQL Injection vulnerability classified under CWE-89, affecting the Visualizer: Tables and Charts Manager for WordPress plugin developed by themeisle. The vulnerability exists in all plugin versions up to and including 3.11.12 due to improper neutralization of special elements in the 'query' parameter. Specifically, the plugin fails to sufficiently escape user-supplied input and does not use prepared statements for SQL queries, allowing attackers with authenticated Contributor-level or higher access to append arbitrary SQL commands. This can lead to unauthorized disclosure of sensitive information from the backend database. The vulnerability does not affect integrity or availability directly but compromises confidentiality. Version 3.11.13 mitigates the risk by raising the minimum required privilege to administrator, reducing the attack surface. The fully patched version 3.11.14 corrects the underlying issue by implementing proper input validation and query preparation. The CVSS v3.1 score is 6.5 (medium severity), reflecting network attack vector, low attack complexity, and the requirement for privileges but no user interaction. No public exploits have been reported, but the vulnerability poses a significant risk to WordPress sites using this plugin, especially those with multiple contributors or administrators. The vulnerability was published on December 2, 2025, and assigned by Wordfence.

For European organizations, this vulnerability could lead to unauthorized disclosure of sensitive data stored in WordPress databases, including user information, business data, or configuration details. Since WordPress powers a significant portion of websites across Europe, and the Visualizer plugin is popular for data visualization, many organizations could be exposed. Attackers with Contributor or higher privileges can exploit this flaw to extract confidential information without needing administrator credentials in versions up to 3.11.12, increasing risk in environments with less restrictive user roles. This could facilitate further attacks such as phishing, identity theft, or lateral movement within networks. The impact is heightened in sectors with strict data protection regulations like GDPR, where data breaches can result in severe legal and financial penalties. Although the vulnerability does not allow data modification or service disruption, the confidentiality breach alone is critical. Organizations relying on WordPress for public-facing or internal portals should consider this a significant threat vector.

European organizations should immediately upgrade the Visualizer plugin to version 3.11.14 or later, which fully patches the vulnerability. Until upgrading, restrict user roles to minimize the number of users with Contributor or higher privileges, ideally limiting to trusted administrators only. Implement strict access controls and monitor user activities for suspicious query parameter usage. Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the 'query' parameter. Conduct regular security audits of WordPress installations and plugins to identify outdated or vulnerable components. Additionally, enforce database permissions to limit the scope of data accessible by the WordPress application user. Educate site administrators about the risks of granting elevated privileges unnecessarily and encourage the use of least privilege principles. Finally, maintain comprehensive backups and incident response plans to quickly recover from potential data breaches.
