Blind SQL Injection in Ultimate Member WordPress Plugin

Publication date: 2026-07-10

Last updated on: 2026-07-10

Assigner: Wordfence

Description
The Ultimate Member – User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin plugin for WordPress is vulnerable to blind SQL Injection via the search parameter in all versions up to, and including, 2.10.1 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. This vulnerability was partially patched in version 2.9.2 when initially addressing CVE-2025-0308.

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 vulnerability exists in the Ultimate Member WordPress plugin, specifically in versions up to and including 2.10.1. It is a blind SQL Injection flaw that occurs via the search parameter. This happens because the plugin does not properly escape user-supplied input and does not sufficiently prepare the SQL query, allowing attackers to append additional SQL commands.

An unauthenticated attacker can exploit this to inject SQL queries into the database, potentially extracting sensitive information without authorization.

This vulnerability was partially addressed in version 2.9.2 as part of a previous fix for CVE-2025-0308, but the issue remains in later versions up to 2.10.1.

Impact Analysis

This vulnerability can allow unauthenticated attackers to extract sensitive information from the database by injecting SQL queries through the search parameter.

Because the attacker does not need any privileges or user interaction, the risk is high.

The impact is primarily confidentiality loss, as indicated by the CVSS score which rates the confidentiality impact as high, while integrity and availability are not affected.

Compliance Impact

This vulnerability allows unauthenticated attackers to perform blind SQL Injection attacks that can extract sensitive information from the database.

Such unauthorized access to sensitive data can lead to violations of data protection regulations like GDPR and HIPAA, which require the protection of personal and sensitive information.

Therefore, exploitation of this vulnerability could result in non-compliance with these common standards and regulations due to potential data breaches.

Mitigation Strategies

To mitigate this vulnerability, you should update the Ultimate Member plugin to a version later than 2.10.1 where the vulnerability has been fixed.

Since the vulnerability was partially patched in version 2.9.2, ensure you are not running any version up to and including 2.10.1.

Additionally, consider restricting access to the vulnerable search parameter or applying web application firewall (WAF) rules to block suspicious SQL injection attempts.
