Sourcecodester Restaurant Management System 1.0 allows an authenticated attacker to upload arbitrary files that can result in code execution. The issue occurs because the application fails to adequately sanitize user-supplied input, e.g., "add a new food" allows .php files.

Sourcecodester Restaurant Management System 1.0 is affected by an admin/staff-exec.php Cross Site Request Forgery vulnerability due to a lack of CSRF protection. This could lead to an attacker tricking the administrator into executing arbitrary code or adding a staff entry via a crafted HTML page.
