JS Help Desk < 2.8.3 - Unauthenticated SQL Injection via 'js-support-ticket-token-tkstatus' Cookie

Description

The plugin is vulnerable to SQL Injection via the 'js-support-ticket-token-tkstatus' cookie due to an incomplete fix for CVE-2023-50839 where a second sink was left with insufficient escaping on the user supplied values 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.
