How to fix?

Upgrade Alpine:3.24 curl to version 8.21.0-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream curl package and not the curl package as distributed by Alpine. See How to fix? for Alpine:3.24 relevant fixed versions and status.

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.
