DescriptionCVE.org

The User Registration & Membership - Free & Paid Memberships, Subscriptions, Content Restriction, User Profile, Custom User Registration & Login Builder plugin for WordPress is vulnerable to SQL Injection via the ‘membership_ids[]’ parameter in all versions up to, and including, 5.1.2 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

AnalysisAI

SQL Injection in User Registration & Membership plugin for WordPress (versions up to 5.1.2) allows authenticated Subscriber-level attackers to extract sensitive database information via unsanitized 'membership_ids[]' parameter. The vulnerability stems from insufficient escaping and lack of prepared statements in SQL query construction, enabling attackers to append arbitrary SQL commands to existing queries. No public exploit code or active exploitation has been identified at the time of analysis.

Technical ContextAI

The vulnerability is a classic SQL Injection (CWE-89) arising from improper input validation and parameterization in database queries. The 'membership_ids[]' parameter, likely used to filter memberships in user registration workflows, is passed directly into SQL queries without adequate escaping or prepared statement binding. WordPress plugins typically interact with the wpdb API; the root cause appears to be direct string concatenation or use of inadequate escaping functions (e.g., esc_attr() instead of database-layer sanitization) rather than parameterized queries using placeholders. The plugin (CPE: cpe:2.3:a:wpeverest:user_registration_&_membership - free & paid memberships, subscriptions, content_restriction, user_profile, custom_user_registration & login_builder) affects the core membership filtering logic, exposing the WordPress user database to unauthorized SELECT operations by any Subscriber or higher-privileged authenticated user.

RemediationAI

Upgrade the User Registration & Membership plugin to version 5.1.3 or later, which includes fixes for the SQL injection vulnerability via improved input escaping and prepared SQL statements. Site administrators should immediately update via the WordPress Plugins dashboard or by downloading the patched version from the official WordPress plugin repository. If immediate patching is not possible, restrict user registration to trusted administrators only, or disable public registration temporarily, as the vulnerability requires authenticated Subscriber-level access.
