SQL Injection in WP TripAdvisor Review Slider Plugin

Publication date: 2026-07-16

Last updated on: 2026-07-16

Assigner: Wordfence

Description
The WP TripAdvisor Review Slider plugin for WordPress is vulnerable to generic SQL Injection via the 'filtersource' parameter in all versions up to, and including, 14.6 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for 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.

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

This vulnerability is a SQL Injection flaw in the WP TripAdvisor Review Slider plugin for WordPress. It exists in versions up to 14.6 due to improper escaping of the 'filtersource' parameter and lack of prepared statements in SQL queries. Authenticated attackers with administrator access or higher can inject malicious SQL code to extract sensitive database information.

Detection Guidance

This vulnerability requires authenticated access with administrator-level privileges or higher. Detection involves checking for unusual SQL query patterns or unauthorized database access attempts. Review WordPress logs for suspicious queries containing 'filtersource' parameter manipulation. Use database monitoring tools to detect unexpected data extraction queries.

Impact Analysis

If you use the affected plugin, an attacker with admin access could steal sensitive data from your WordPress database, such as user credentials, personal information, or other confidential data stored in the site.

Compliance Impact

This vulnerability could lead to unauthorized data access, violating GDPR (data protection) and HIPAA (health data privacy) by exposing personal or sensitive information. Compliance may be compromised if user data is leaked due to the flaw.

Mitigation Strategies

Immediately update the WP TripAdvisor Review Slider plugin to the latest version beyond 14.6. If an update is unavailable, consider disabling or removing the plugin entirely. Implement strict access controls to limit administrator-level access. Monitor database activity for suspicious queries involving the 'filtersource' parameter.
