CVE-2025-6189 is a time-based SQL Injection vulnerability affecting the Duplicate Page and Post WordPress plugin, versions up to and including 2.9.5. The root cause is insufficient escaping and lack of proper preparation of the 'meta_key' parameter in SQL queries, which allows an authenticated attacker with Contributor-level privileges or higher to inject arbitrary SQL commands. This injection occurs because the plugin directly incorporates user-supplied input into SQL statements without adequate sanitization or use of parameterized queries. The vulnerability enables attackers to append additional SQL queries to existing ones, facilitating extraction of sensitive data from the WordPress database. The attack vector requires authentication but no user interaction beyond that. The vulnerability does not affect integrity or availability but has a high impact on confidentiality. No patches are currently linked, and no known exploits have been reported in the wild. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N) indicates network attack vector, low complexity, requiring privileges, no user interaction, unchanged scope, and high confidentiality impact. The vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command).

The primary impact of CVE-2025-6189 is unauthorized disclosure of sensitive information stored in the WordPress database, which may include user credentials, personal data, or site configuration details. Since the vulnerability requires Contributor-level access, attackers must first compromise or register an account with such privileges, which is feasible on sites allowing user registrations or with weak access controls. Exploitation could lead to data breaches, privacy violations, and potential further attacks leveraging the extracted data. Although the vulnerability does not affect data integrity or site availability, the confidentiality breach alone can damage organizational reputation, lead to regulatory penalties, and erode user trust. Organizations relying on the Duplicate Page and Post plugin for content management are at risk, especially those with high-value data or large user bases. The lack of known exploits in the wild suggests limited current exploitation but also means organizations should proactively address the vulnerability before attackers develop weaponized exploits.

Organizations should immediately audit their WordPress installations to identify the use of the Duplicate Page and Post plugin, especially versions up to 2.9.5. Until an official patch is released, administrators should restrict Contributor-level and higher access to trusted users only, minimizing the risk of exploitation. Implementing Web Application Firewalls (WAFs) with custom rules to detect and block suspicious SQL injection patterns targeting the 'meta_key' parameter can provide temporary protection. Monitoring database query logs for unusual or time-delayed queries may help detect attempted exploitation. Site owners should also enforce strong authentication and user registration policies to prevent unauthorized account creation with elevated privileges. Once a patch becomes available, prompt updating of the plugin is critical. Additionally, adopting security best practices such as principle of least privilege for user roles and regular security audits will reduce exposure to similar vulnerabilities.
