Time-Based Blind SQL Injection in Tainacan WordPress Plugin

Publication date: 2026-07-08

Last updated on: 2026-07-08

Assigner: Wordfence

Description
The Tainacan plugin for WordPress is vulnerable to time-based blind SQL Injection via the 'geoquery' parameter in all versions up to and including 1.0.3 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.

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 Tainacan plugin for WordPress has a time-based blind SQL Injection vulnerability in the 'geoquery' parameter in all versions up to and including 1.0.3. This vulnerability arises because the plugin does not properly escape or prepare the user-supplied 'geoquery' parameter before including it in SQL queries.

As a result, unauthenticated attackers can append additional malicious SQL queries to the existing ones, potentially extracting sensitive information from the database.

Impact Analysis

This vulnerability allows unauthenticated attackers to perform SQL Injection attacks, which can lead to unauthorized extraction of sensitive data from the database.

Because the attack is time-based and blind, attackers can systematically retrieve information without direct feedback, making it possible to compromise confidential information stored by the plugin.

Mitigation Strategies

To mitigate the SQL injection vulnerability in the Tainacan WordPress plugin, you should update the plugin to a version that includes the fix addressing the issue.

The fix involves proper validation and sanitization of the 'geoquery' parameter, including splitting and validating coordinate values, converting them to float, and using WordPress's database abstraction layer's prepare() method to safely insert values into SQL queries.

If updating is not immediately possible, consider disabling or restricting access to the vulnerable functionality related to geospatial queries until the patch can be applied.
