WordPress IWS Geo Form Fields plugin through 1.0 contains a SQL injection vulnerability. The plugin does not properly escape a parameter before using it in a SQL statement via an AJAX action available to unauthenticated users. An attacker can possibly obtain sensitive information, modify data, and/or execute unauthorized administrative operations in the context of the affected site.
Successful exploitation of this vulnerability could allow an attacker to execute arbitrary SQL queries, potentially leading to unauthorized access, data leakage, or further compromise of the affected WordPress site.
Update to the latest version of the WordPress IWS Geo Form Fields plugin (>=1.1) or apply the vendor-supplied patch to mitigate the SQL Injection vulnerability.
