Pharmacy Sales and Inventory System CVE-2026-7199

Primary mitigation is to discontinue use of SourceCodester Pharmacy Sales and Inventory System 1.0 in production environments, as no vendor-released patch has been identified and SourceCodester projects are typically educational code samples not maintained for security updates. If the application must remain operational, immediately implement these SPECIFIC compensating controls: (1) Deploy a web application firewall (WAF) with SQL injection signatures to block malicious payloads in the ID parameter of /ajax.php requests - note this is a detection-based control that may be bypassed with encoding or obfuscation. (2) Restrict network access to /ajax.php using IP allowlisting at the web server or firewall level, limiting access to only trusted internal IP ranges - this prevents remote exploitation but breaks functionality for legitimate remote users. (3) Review application code in /ajax.php and replace vulnerable dynamic SQL with parameterized queries or prepared statements using PHP PDO/mysqli_prepare - example: replace '$id = $_POST["ID"]' concatenation with bound parameters. (4) Apply principle of least privilege to the database account used by the application, revoking DELETE, DROP, FILE privileges to limit post-exploitation impact - may break intended delete_product functionality requiring code refactoring. For organizations using this as a learning platform, migrate to a modern, actively maintained pharmacy management system with security support.
