If you find similar encoded strings, decode them with curl itself:

# Encoded version of curl file:///etc/passwd encoded="file%3A%2F%2F%2Fetc%2Fpasswd" curl "$encoded"

Understanding how curl , URL-encoded strings, and the local file scheme interact is essential for system administrators, DevOps engineers, and security professionals. Breaking Down the Keyword Syntax While curl is famous for HTTP and HTTPS

The core of this keyword lies in URL encoding (also known as percent-encoding). When systems pass uniform resource identifiers (URIs) through certain environments like web browsers, APIs, or configuration scripts, special characters must be converted into a safe ASCII format.

The general syntax for accessing a local file with curl is: curl file:///path/to/file You can write a script that

SSRF occurs when an attacker induces a server-side application to make HTTP or file requests to an unexpected location. If an application accepts a URL input from a user, passes it to a backend cURL script, and fails to sanitize the inputs, an attacker can input file:/// instead of https:// .

In the world of web development, command-line tools have become an essential part of a developer's arsenal.
