CVE-2026-76048 is a SQL injection vulnerability in SourceCodester Simple Online Food Ordering System 1.0. The issue exists in an unspecified function within the /admin/ajax.php?action=login file, where the Username parameter is not properly sanitized. This allows an unauthenticated remote attacker to inject SQL commands by manipulating the Username argument. Exploit code is publicly available, but there is no evidence of widespread exploitation. No official patch or remediation guidance has been provided by the vendor as of the publication date.

Successful exploitation could allow an attacker to execute arbitrary SQL commands on the backend database, potentially leading to unauthorized data access or modification. Since the vulnerability is remotely exploitable without authentication, it increases the risk of compromise. However, the CVSS vector indicates low attack complexity and no privileges required, but with low confidentiality, integrity, and availability impacts, consistent with medium severity.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, it is recommended to implement input validation and sanitization on the Username parameter, restrict access to the affected endpoint, and monitor for suspicious activity related to SQL injection attempts.
