## Technical details

The Tainacan plugin for WordPress is vulnerable to time-based blind SQL injection due to improper neutralization of special elements in the 'geoquery' parameter. Specifically, the 'class-tainacan-geocoordinate-helper.php' component fails to sufficiently escape user-supplied input and lacks proper SQL query preparation. An unauthenticated attacker can exploit this by sending crafted network requests to append malicious SQL commands to existing queries. This allows for the exfiltration of sensitive data from the WordPress database based on the time delay of the server's response. A fix has been committed to the GitHub repository.
