Deeper analysis

CVE-2026-27039 is an Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability that enables Blind SQL Injection in the AA-Team WZone Woozone WordPress plugin. This flaw affects WZone versions from n/a through 14.0.31 and is classified under CWE-89.

The vulnerability carries a CVSS v3.1 base score of 8.5 (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:L), indicating it is exploitable over the network with low complexity by low-privileged users, requiring no user interaction. Successful exploitation allows attackers to achieve high confidentiality impact, such as extracting sensitive data from the database via blind SQL injection techniques, alongside low availability impact and a change in scope.

Patchstack advisories document the SQL injection vulnerability in the WordPress WZone plugin up to version 14.0.31, providing details on the issue at https://patchstack.com/database/Wordpress/Plugin/woozone/vulnerability/wordpress-wzone-plugin-14-0-31-sql-injection-vulnerability?_s_id=cve.
