HIGH 7.5

DescriptionCVE.org

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.

AnalysisAI

Unauthenticated SQL injection in the ARMember Premium WordPress plugin (versions up to and including 7.3.1) allows remote attackers to extract sensitive database contents by injecting crafted values into the 'order' and 'orderby' parameters of the arm_directory_paging_action AJAX endpoint. With CVSS 7.5 reflecting confidentiality-only impact and no public exploit identified at time of analysis, the bug is reachable without credentials but EPSS data was not provided to estimate exploitation likelihood.

Technical ContextAI

ARMember Premium is a commercial WordPress membership plugin (CPE: cpe:2.3:a:armember:armember_premium_…:*) that exposes admin-ajax handlers for front-end directory browsing. The vulnerable code path is the arm_get_directory_members() function invoked via the 'arm_directory_paging_action' AJAX action, where user-supplied 'order' and 'orderby' values are concatenated into an SQL ORDER BY clause without going through wpdb->prepare() or proper escaping/whitelisting. This is a textbook CWE-89 (Improper Neutralization of Special Elements used in an SQL Command), and because ORDER BY cannot use parameter placeholders directly in MySQL, plugins must validate against an allow-list - ARMember failed to do so, enabling UNION-based or time-based extraction.

RemediationAI

No vendor-released patch version is identified in the available data; the Wordfence advisory at https://www.wordfence.com/threat-intel/vulnerabilities/id/b5f6d2a2-ad3e-4afc-b6fd-745881d85b6b should be monitored for an updated build above 7.3.1, and CodeCanyon licensees should check https://codecanyon.net/item/armember-complete-wordpress-membership-system/17785056 for a new download. Until a fix ships, deactivate the ARMember Premium plugin if the member directory feature is non-essential (this disables membership signup and gated content as a side effect), or place a WAF rule in front of wp-admin/admin-ajax.php that blocks requests where action=arm_directory_paging_action contains SQL metacharacters in the 'order' or 'orderby' parameters (false positives are low because both should be limited to ASC/DESC and a small column allow-list). Database-level mitigations such as restricting the WordPress DB user to SELECT on wp_users will not help here because the injection occurs in a SELECT context.
