Curl-url-file-3a-2f-2f-2f -

Allowing arbitrary input strings like file:/// into a curl execution loop poses massive security liabilities. If a web application accepts a user-supplied URL and passes it directly to a backend curl request, it creates a vulnerability known as . The Attack Vector

So, curl-url-file-3A-2F-2F-2F translates to a URL that might look something like http://example.com/path/to/file , but in a URL-encoded form. Specifically, it seems there might have been a misunderstanding in the direct representation; typically, a URL like http://example.com/path/to/file wouldn't be represented with 3A or 2F in such a context, as those are usually used for encoding. However, understanding that curl can work with URLs that are properly encoded or specified is crucial. curl-url-file-3A-2F-2F-2F

In essence, file:/// translates to "the beginning of the path to a file or directory from the root of the filesystem." When you issue a command like curl file:///etc/hosts , the file:/// part tells curl to look on the local machine, and the /etc/hosts part is the absolute path to the file you want to read.
