CVE-2025-11972 is an SQL Injection vulnerability classified under CWE-89 found in the 'Tag, Category, and Taxonomy Manager – AI Autotagger with OpenAI' WordPress plugin developed by stevejburge. The flaw exists in all versions up to and including 3.40.0, specifically in the handling of the 'post_types' parameter. This parameter is insufficiently escaped and the SQL queries are not properly prepared, allowing an attacker with Editor-level or higher privileges to append arbitrary SQL commands to existing queries. This improper neutralization of special elements in SQL commands can be exploited to extract sensitive information from the backend database, such as user data or site configuration details. The vulnerability requires authenticated access with elevated privileges but does not require additional user interaction. The CVSS 3.1 base score is 4.9 (medium severity), reflecting the network attack vector, low attack complexity, and high privileges required. The impact is limited to confidentiality as integrity and availability are not affected. No patches or known exploits are currently available, but the vulnerability is publicly disclosed and should be addressed promptly. The plugin is used in WordPress environments that leverage AI-based tagging and taxonomy management, making it a target in content-heavy websites.

For European organizations, this vulnerability poses a risk of sensitive data exposure from WordPress databases, which may include personal data protected under GDPR. Attackers with Editor-level access could exploit this flaw to extract confidential information, potentially leading to privacy violations, reputational damage, and regulatory penalties. Since Editors typically manage content but do not have full administrative rights, the attack surface is somewhat limited but still significant in collaborative environments. The confidentiality breach could expose user credentials, internal content, or configuration data, which can be leveraged for further attacks. The absence of impact on integrity and availability reduces the risk of site defacement or downtime but does not eliminate the threat to data privacy. Organizations relying on this plugin for AI-assisted content management should consider the risk especially in sectors with strict data protection requirements such as finance, healthcare, and government. The medium severity score suggests prioritizing remediation but not immediate emergency response unless combined with other vulnerabilities.

1. Monitor the plugin vendor’s official channels for security patches and apply updates immediately once available. 2. Until a patch is released, restrict Editor-level privileges to trusted users only and review user roles to minimize exposure. 3. Implement Web Application Firewall (WAF) rules to detect and block suspicious SQL injection patterns targeting the 'post_types' parameter. 4. Employ input validation and sanitization at the application or server level to enforce strict type and content checks on parameters passed to the plugin. 5. Conduct regular security audits and database access monitoring to detect unusual query patterns or data access. 6. Consider disabling or replacing the plugin with alternatives that follow secure coding practices if timely patching is not feasible. 7. Educate content editors about the risks of elevated privileges and enforce the principle of least privilege. 8. Backup WordPress databases regularly to ensure recovery in case of compromise. These steps go beyond generic advice by focusing on privilege management, proactive monitoring, and interim protective controls.
