A URL scheme tells the browser or operating system how to access a resource. The file scheme is used to access files directly on the user's local filesystem.

This format is immediately recognizable: it's a custom URI scheme, a specific type of URL that an application or framework might use for its own internal functions. The triple slash ( :/// ) is a strong clue that this scheme is designed to interact with the .
The string appears to be a reference to a Capture The Flag (CTF) challenge or a specific security research topic involving Server-Side Request Forgery (SSRF) . In URL encoding, 3A-2F-2F-2F translates to ://// , which is often used as a payload to bypass security filters when attempting to access local files via the file:/// protocol.

The MDN Web Docs Fetch API dictates that web applications operate within an origin sandbox. An origin is defined by its protocol, domain, and port. Because https:// and file:/// are entirely different protocols, they represent different origins. A remote website has no inherent CORS privileges to read from your local machine's drive. 2.
