SQL Injection in WP Bulk Delete WordPress Plugin

Publication date: 2026-07-16

Last updated on: 2026-07-16

Assigner: Wordfence

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.

CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

The WP Bulk Delete plugin for WordPress has a SQL Injection vulnerability in versions up to 1.4.2. The issue occurs due to insufficient escaping of the 'delete_user_roles' parameter and lack of proper SQL query preparation. Attackers with admin access can inject malicious SQL queries to extract sensitive database information.

Detection Guidance

This vulnerability requires authenticated access with administrator-level privileges. Check WordPress admin logs for suspicious SQL-related POST requests targeting the 'delete_user_roles' parameter. Review database query logs for unusual queries containing appended SQL commands.

Impact Analysis

If you use the WP Bulk Delete plugin with versions up to 1.4.2, an authenticated attacker with admin privileges could exploit this to steal sensitive data from your WordPress database, such as user credentials or other confidential information.

Compliance Impact

This vulnerability could lead to unauthorized access to personal data, violating GDPR and HIPAA compliance. Exposure of sensitive user information may result in legal penalties, data breach notifications, and reputational damage.

Mitigation Strategies

Immediately update the WP Bulk Delete plugin to the latest version. If an update is unavailable, disable the plugin until a patch is released. Restrict administrator-level access to trusted users only.
