Simply Poll 1.4.1 Plugin for WordPress SQL Injection

Simply Poll 1.4.1 plugin for WordPress contains an SQL injection vulnerability that allows unauthenticated attackers to extract database information by injecting SQL code through the 'pollid' POST parameter. Attackers can send requests to the admin-ajax.php endpoint with the 'spAjaxResults' action and malicious 'pollid' values to execute arbitrary SQL queries and read sensitive data from the WordPress database.
