Summary
password leak with netrc and user in URL
Details

When asking curl to use a .netrc file to find credentials and at the same time specifying a URL with a username (without a password), like https://user@example.com/, curl could wrongly get and use the password for another user set in the .netrc file for that host if such a one exists and there is no match for the specified user.
