An SQL Injection vulnerability exists in Redeight CMS version 1.0 via the "userEmail" parameter in the POST "/admin/index.php" login endpoint. The application fails to sanitize user input and directly interpolates it into SQL queries without using prepared statements, which allows unauthenticated remote attackers to execute arbitrary SQL commands and extract sensitive database information.
