ARMember WordPress Plugin Vulnerable to SQL Injection
The ARMember – Membership Plugin for WordPress, in all versions up to and including 4.0.60, is susceptible to a time-based blind SQL Injection. This vulnerability, tracked as CVE-2026-7649, stems from inadequate escaping of the ‘orderby’ parameter and insufficient preparation of existing SQL queries, as detailed by the National Vulnerability Database. The CVSS score for this flaw is 7.5 (HIGH), indicating significant risk.
This critical flaw enables unauthenticated attackers to inject additional SQL queries, potentially extracting sensitive data directly from the underlying database. The ‘orderby’ parameter, when exploited, provides a clear pathway for data exfiltration, bypassing standard security controls due to the plugin’s internal processing deficiencies.
Defenders must prioritize patching. This isn’t theoretical; SQL injection remains a top attack vector for a reason. Attackers, even those with limited skills, can automate exploitation to enumerate database schemas and dump user credentials or other proprietary information. The absence of authentication requirements makes this particularly dangerous, allowing broad exploitation against any exposed instance.
What This Means For You
- If your organization uses the ARMember plugin for WordPress, you are directly exposed to unauthenticated data theft. Immediately verify your plugin version and apply the latest available patch to mitigate CVE-2026-7649. Audit your WordPress database logs for any suspicious queries or unauthorized access attempts from the past several weeks.
