How to fix?

Upgrade Minimos:latest curl-doc to version 8.19.0-r0 or higher.

NVD Description

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

When an OAuth2 bearer token is used for an HTTP(S) transfer, and that transfer performs a redirect to a second URL, curl could leak that token to the second hostname under some circumstances.

If the hostname that the first request is redirected to has information in the used .netrc file, with either of the machine or default keywords, curl would pass on the bearer token set for the first host also to the second one.
