A Cross-Site Request Forgery (CSRF) vulnerability was found in SourceCodester Best House Rental Management System v1.0. This could lead to an attacker tricking the administrator into adding/modifying/deleting valid tenant data via a crafted HTML page, as demonstrated by a Delete Tenant action at the /rental/ajax.php?action=delete_tenant.
