Description Jon Moroney 2026-07-06 20:23:14 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

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.

This bug appears to have been reported against 'rawhide' during the Fedora Linux 45 development cycle.
Changing version to 45.
