ARMember WordPress plugin versions through 4.0.60 contain an unauthenticated SQL injection vulnerability in the members directory that allows attackers to extract sensitive database information…

How to fix or mitigate CVE-2026-7649?

Within 24 hours: Disable or remove ARMember plugin from all WordPress installations; audit web server logs for suspicious 'orderby' parameter queries. Within 7 days: Contact ARMember vendor for patch availability status and timeline; implement Web Application Firewall (WAF) rules to block SQL injection patterns in the 'orderby' parameter as interim mitigation. Within 30 days: Once vendor releases patched version, update ARMember to the fixed release; conduct forensic review of database access logs for evidence of exploitation; reset database credentials if compromise is suspected.

HIGH 7.5

DescriptionCVE.org

The ARMember - Membership Plugin, Content Restriction, Member Levels, User Profile & User signup plugin for WordPress is vulnerable to time-based blind SQL Injection via the 'orderby' parameter in all versions up to, and including, 4.0.60 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. 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

Time-based blind SQL injection in ARMember WordPress plugin versions up to 4.0.60 allows unauthenticated remote attackers to extract sensitive database information via the 'orderby' parameter. The vulnerability stems from insufficient input sanitization in the members directory and shortcode handling classes, enabling attackers to append malicious SQL queries without authentication (CVSS 7.5, AV:N/AC:L/PR:N/UI:N). EPSS data and active exploitation status not available at time of analysis, but the lack of authentication requirements and low attack complexity make this a high-priority remediation target for WordPress sites using ARMember for membership management or content restriction.

Technical ContextAI

This vulnerability affects the ARMember WordPress plugin (CPE: cpe:2.3:a:reputeinfosystems:armember_-_membership_plugin), specifically in the class.arm_members_directory.php and class.arm_shortcodes.php files. The flaw is classified as CWE-89 (SQL Injection), occurring when user-supplied input to the 'orderby' parameter is not properly escaped or parameterized before being incorporated into SQL queries. Time-based blind SQL injection allows attackers to infer database contents by measuring response times to specially crafted queries containing conditional delays (e.g., using SQL SLEEP or WAITFOR functions). The vulnerable code exists in both the member directory listing functionality (line 1019 of class.arm_members_directory.php) and shortcode processing (lines 36 and 434 of class.arm_shortcodes.php), suggesting multiple attack surfaces within the plugin's member management features. WordPress plugins using direct SQL queries without WordPress's $wpdb->prepare() method are particularly susceptible to this class of vulnerability.

RemediationAI

Immediately update ARMember plugin to the latest version above 4.0.60 from the WordPress plugin repository or vendor website. While the exact patched version number is not independently confirmed in the provided data, updates released after version 4.0.60 should address this SQL injection vulnerability. Site administrators should verify the changelog at https://wordpress.org/plugins/armember-membership/ for security fix confirmation before deploying. If immediate patching is not possible, implement the following compensating controls: (1) Deploy a Web Application Firewall (WAF) with SQL injection detection rules to filter malicious 'orderby' parameter values, noting this may break legitimate sorting functionality in member directories; (2) Restrict access to pages using ARMember shortcodes or member directory features to authenticated users only via WordPress access controls, reducing attack surface but limiting plugin functionality; (3) Enable comprehensive database query logging to detect exploitation attempts, though this adds performance overhead; (4) Consider temporarily deactivating ARMember plugin if membership features are non-critical, which eliminates the attack vector but disables all content restriction and membership management capabilities. After patching, review database logs for suspicious query patterns (unusual SLEEP/WAITFOR commands, extended query times) and conduct a security audit of user data to identify potential unauthorized access.
