WordPress vulnerability analysis and mitigation

The Duplicate Page and Post plugin for WordPress contains a time-based SQL Injection vulnerability (CVE-2025-6189) discovered in September 2025. The vulnerability affects all versions up to and including 2.9.5. This security flaw exists in the 'meta_key' parameter due to insufficient escaping of user-supplied input and inadequate SQL query preparation (NVD CVE).

The vulnerability is classified as an SQL Injection (CWE-89) with a CVSS v3.1 base score of 6.5 (Medium). The attack requires network access and low privilege level authentication. The vulnerability allows authenticated attackers with Contributor-level access or higher to append additional SQL queries to existing database queries (NVD CVE).

When successfully exploited, the vulnerability enables authenticated attackers to extract sensitive information from the WordPress database. The attack primarily affects the confidentiality of the system, as indicated by the CVSS metrics showing high confidentiality impact but no impact on integrity or availability (NVD CVE).

Users should update the Duplicate Page and Post plugin to a version newer than 2.9.5 when available. Until a patch is released, site administrators should consider restricting Contributor-level access or temporarily disabling the plugin if the functionality is not critical (NVD CVE).
