CVE-2025-6189 is a medium-severity SQL Injection vulnerability affecting the WordPress plugin 'Duplicate Page and Post' developed by arjunthakur. The vulnerability exists in all versions up to and including 2.9.5. It arises from improper neutralization of special elements in SQL commands (CWE-89), specifically due to insufficient escaping of the 'meta_key' parameter supplied by users and the lack of adequate preparation of the SQL query. This flaw allows authenticated attackers with Contributor-level access or higher to perform time-based SQL Injection attacks by appending additional SQL queries to existing ones. The exploitation does not require user interaction but does require authentication with at least Contributor privileges. The vulnerability can be leveraged to extract sensitive information from the backend database, impacting confidentiality. The CVSS v3.1 score is 6.5 (medium), with attack vector being network-based, low attack complexity, requiring privileges, no user interaction, unchanged scope, and high confidentiality impact but no integrity or availability impact. No known exploits are currently reported in the wild. The vulnerability was reserved in June 2025 and published in September 2025. No patches or fixes have been linked yet, indicating that affected users must monitor for updates or apply mitigations proactively. The vulnerability is significant because WordPress is widely used across Europe, and the Duplicate Page and Post plugin is popular for content management, making this a relevant threat vector for website administrators and organizations relying on WordPress for their web presence.

For European organizations, this vulnerability poses a risk primarily to websites and web applications running WordPress with the affected Duplicate Page and Post plugin versions. Exploitation can lead to unauthorized disclosure of sensitive data stored in the database, such as user credentials, personal data, or business-critical information, violating GDPR and other data protection regulations. Since the attack requires authenticated access at Contributor level or above, insider threats or compromised accounts can be leveraged to exploit this vulnerability. The confidentiality breach could result in reputational damage, regulatory fines, and loss of customer trust. However, the vulnerability does not allow modification or deletion of data (no integrity or availability impact), limiting the scope of damage. Organizations with public-facing WordPress sites, especially those in sectors like e-commerce, finance, healthcare, or government, where sensitive data is processed, are at higher risk. The lack of known exploits in the wild currently reduces immediate threat but does not eliminate risk, especially as attackers may develop exploits over time.

1. Immediate mitigation involves restricting Contributor-level access to trusted users only and reviewing user roles to minimize privilege exposure. 2. Monitor WordPress plugin updates closely and apply patches from the vendor as soon as they are released. 3. Implement Web Application Firewalls (WAFs) with rules to detect and block SQL Injection attempts targeting the 'meta_key' parameter. 4. Employ database query parameterization and input validation where possible, including custom hardening of the plugin code if feasible. 5. Conduct regular security audits and penetration testing focusing on WordPress plugins and user privilege management. 6. Enable detailed logging and monitoring of database queries and user activities to detect anomalous behavior indicative of exploitation attempts. 7. Educate site administrators and content contributors about the risks of privilege misuse and encourage strong authentication mechanisms such as MFA to reduce account compromise risk.
