A SQL injection vulnerability was found in YzmCMS 7.5. The issue occurs in the get_arrchildid() function within application/admin/controller/category.class.php, where the user-controlled parentid parameter is concatenated directly into a FIND_IN_SET() SQL clause without proper sanitization. This allows an authenticated administrator to execute arbitrary SQL queries via boolean-based blind injection, potentially leading to full database compromise.
