## What is CVE-2026-5073?

CVE-2026-5073 is a high-severity SQL injection vulnerability in ARMember Premium – Membership Plugin, Content Restriction, Member Levels, User Profile & User signup, published on 2 Jun 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

The ARMember Premium plugin for WordPress is vulnerable to SQL Injection via the 'order' parameter of the 'arm_directory_paging_action' AJAX action in all versions up to, and including, 7.3.1. This is due to insufficient escaping on the user-supplied 'order' and 'orderby' parameters and the lack of sufficient preparation on the existing SQL query in the `arm_get_directory_members()` function. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

Weakness: CWE-89 (Improper Neutralization of Special Elements used in an SQL Command)
