file:///root/.aws/config
If an attacker can read /root/.aws/config , they may also be able to read /root/.aws/credentials (often located in the same directory). Having both files allows an attacker to assume the identity of the root user’s AWS account. With those credentials, they can:

– Researchers found an SSRF flaw in Tesla’s Kubernetes console that could have allowed attackers to access internal cloud resources.
The file:/// schema tells a system's internal file-fetching or rendering utility to read a file from the local file system rather than requesting a web page over http:// or https:// . If a web application poorly sanitizes input in a URL-fetching feature (such as an "upload via URL" or "preview link" function), it will execute this request locally. 3. The Target: /root/.aws/config file:///root/
: Disable the file:// URI scheme in all user-facing fetch commands. Applications should ideally only allow http:// or https:// .

The config file isn't just for regions. You can tune performance. For example, if you are uploading massive files to S3, you can increase the transfer concurrency specifically for S3 operations:
url=file:///root/.aws/credentials
If this URL is used within a specific application or context you're developing, you might need to adjust the path to fit your actual file system structure or requirements.
Most developer implementations of URL-fetching utilities (like curl in PHP, requests in Python, or fetch in Node.js) natively support multiple protocols. If a developer forgets to restrict the allowed protocols exclusively to http:// and https:// , the underlying library will happily process the file:// wrapper. This opens the door to Local File Inclusion (LFI) via an SSRF vector, allowing bad actors to read any file on the server that the application process has permissions to access.
