Properly handling file paths in web applications is crucial for security. By normalizing paths, validating user input, and restricting access to intended directories, developers can significantly reduce the risk of path traversal and other file system-related attacks. Always stay informed about potential security threats and follow best practices to secure your applications. If you must accept file names, validate the

If you must accept file names, validate the input against a strict whitelist of allowed characters (e.g., lowercase letters and numbers only). Reject anything containing dots or slashes. 3. Utilize Built-in Path Functions
