CVE-2026-8926
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://[email protected]/`, 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.
