A path traversal vulnerability (also known as directory traversal) occurs when a script uses user-supplied input to construct a file path without adequate sanitization. Attackers can use sequences like ../ (dot-dot-slash) to navigate outside the intended directory and access sensitive files. For example, a malicious request might look like: Understanding the pattern is key to maintaining a
