The flaw allows an attacker to manipulate file paths to access directories that should be inaccessible. By sending crafted requests to the server, an attacker can traverse the directory tree to leak local files, including sensitive data.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-456910579\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>Below is a conceptual example of how this vulnerability might be exploited.
