CVE-2025-2221: CWE-89 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in whyun WPCOM Member
The WPCOM Member plugin for WordPress is vulnerable to time-based SQL Injection via the ‘user_phone’ parameter in all versions up to, and including, 1.7.6 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.
AI Analysis
Technical Summary
CVE-2025-2221 is a high-severity SQL Injection vulnerability in the WPCOM Member plugin for WordPress, affecting all versions up to 1.7.6. The issue arises from insufficient escaping and lack of prepared statements for the 'user_phone' parameter, enabling unauthenticated attackers to perform time-based SQL Injection attacks. This can lead to unauthorized extraction of sensitive data from the backend database. The vulnerability is network exploitable without authentication and does not require user interaction.
Potential Impact
Successful exploitation allows attackers to extract sensitive information from the database without authentication, potentially compromising confidentiality. The vulnerability does not impact integrity or availability according to the CVSS vector. No known exploits in the wild have been reported at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider disabling or restricting access to the vulnerable plugin. Applying web application firewall (WAF) rules to detect and block SQL Injection attempts targeting the 'user_phone' parameter may provide temporary mitigation.
