MEDIUM CVE-2026-15727 Deferred

WP Bulk Delete user-role filter permits SQL injection

WP Bulk Delete 1.4.2 and earlier places delete_user_roles into a database query without sufficient preparation. An authenticated administrator can inject additional SQL and extract information from the WordPress database; the administrator prerequisite limits exposure but does not make a compromised admin session safe.

Source record

Technical description

The WP Bulk Delete plugin for WordPress is vulnerable to generic SQL Injection via the 'delete_user_roles' parameter in all versions up to, and including, 1.4.2 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 administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. wp_unslash() is applied to the raw POST body before parse_str() decomposes it, stripping WordPress magic-quotes protection and leaving attacker-controlled values fully unescaped prior to reaching the SQL sink.
