Administrator SQL injection via unvalidated submission identifier

Published Mar 7, 2022 · Updated Aug 3, 2024

SQL injection in Hotscot Contact Form before 1.3 allows remote authenticated users to alter database queries through a crafted submission ID. The view-submission handler places the GET sub_id parameter into an SQL statement without sanitizing, escaping, or validating it. Administrator access is required, and successful exploitation can expose, modify, or delete data accessible to the WordPress database account.
