CVE-2026-15906 describes a SQL Injection vulnerability (CWE-89) in the Premium Packages – Sell Digital Products Securely WordPress plugin by codename065. The issue arises from improper neutralization of special elements in the 'orderby' parameter, allowing authenticated attackers with admin-level access to inject additional SQL commands into existing queries. This vulnerability affects all versions up to and including 7.0.4. The CVSS 3.1 base score is 6.5 (medium severity), reflecting network attack vector, low attack complexity, and required privileges at the level of an authenticated user with privileges. No vendor advisory or patch information is currently available, and no known exploits in the wild have been reported.

An attacker with admin-level access can exploit this vulnerability to execute arbitrary SQL commands appended to legitimate queries. This can lead to unauthorized disclosure of sensitive information from the database. The vulnerability does not directly impact integrity or availability according to the CVSS vector, but confidentiality is rated high.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict admin-level access to trusted users only and monitor for suspicious activity related to the 'orderby' parameter. Avoid exposing this plugin on publicly accessible sites without additional protective controls.
