CVE-2026-8926
Description
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.
