SourceCodester Simple Online Food Ordering System 1.0 contains a SQL injection vulnerability in the /admin/ajax.php?action=save_menu file. The vulnerability arises from improper sanitization of the ID argument, allowing remote attackers to inject SQL commands. This vulnerability is publicly known and can be exploited without authentication. The CVSS 4.0 vector indicates network attack vector, low complexity, no privileges or user interaction required, and low to limited impact on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary SQL commands on the backend database remotely. This may lead to unauthorized data access, modification, or deletion depending on the database permissions. The medium severity reflects the potential for partial compromise of data confidentiality and integrity but not full system compromise.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided. Until a patch is available, restrict access to the vulnerable endpoint and apply web application firewall (WAF) rules to detect and block SQL injection attempts targeting the ID parameter.
