CVE-2026-2495 is a SQL Injection vulnerability identified in the WPNakama plugin for WordPress, which facilitates team and multi-client collaboration, editorial, and project management functions. The vulnerability specifically targets the 'order' parameter in the REST API endpoint '/wp-json/WPNakama/v1/boards'. Due to insufficient escaping and lack of prepared statements in the SQL query construction, attackers can inject arbitrary SQL commands. This injection can be performed without any authentication or user interaction, making it remotely exploitable over the network. The injection allows attackers to append additional SQL queries, potentially leading to unauthorized disclosure of sensitive information stored in the backend database. The vulnerability affects all versions up to and including 0.6.5 of the plugin. While no public exploits have been reported yet, the nature of the vulnerability and its exposure via a REST API endpoint make it a critical concern. The CVSS 3.1 base score of 7.5 reflects its high impact on confidentiality with no impact on integrity or availability. The vulnerability is categorized under CWE-89, which relates to improper neutralization of special elements in SQL commands. The lack of patches at the time of reporting necessitates immediate mitigation efforts by affected organizations.

For European organizations, the impact of CVE-2026-2495 is significant due to the potential unauthorized disclosure of sensitive data from the backend databases of WordPress sites using the WPNakama plugin. This could include confidential project information, client data, or internal communications, leading to reputational damage, regulatory non-compliance (e.g., GDPR violations), and potential financial losses. Since the vulnerability is exploitable without authentication, attackers can remotely access sensitive data without needing valid credentials, increasing the attack surface. Organizations relying on WordPress for collaboration and project management are particularly vulnerable, especially those in sectors with stringent data protection requirements such as finance, healthcare, and government. The exploitation could also serve as a foothold for further attacks, including lateral movement or data exfiltration. The absence of known exploits in the wild currently provides a window for proactive defense, but the ease of exploitation and high confidentiality impact necessitate urgent remediation.

1. Monitor the vendor’s official channels for patches addressing CVE-2026-2495 and apply updates immediately upon release. 2. Until patches are available, implement strict input validation and sanitization on the 'order' parameter at the web application level to block malicious payloads. 3. Deploy Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the vulnerable REST API endpoint. 4. Restrict access to the REST API endpoints to authenticated users or trusted IP ranges where feasible, reducing exposure. 5. Conduct thorough security audits and penetration testing focusing on REST API endpoints to identify similar injection flaws. 6. Regularly review and monitor logs for unusual query patterns or failed injection attempts to detect exploitation attempts early. 7. Educate development teams on secure coding practices, emphasizing the use of prepared statements and parameterized queries to prevent SQL injection. 8. Consider isolating or disabling the WPNakama plugin if it is not critical to operations until a secure version is available.
