How to fix?

Upgrade Alpine:3.23 curl to version 8.23.0-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:3.23 relevant fixed versions and status.

When invoked with --remote-header-name (-J), curl fails to preserve its documented anti-clobbering protection if an intermediate 103 Early Hints response precedes the final HTTP response, or if an ETag header is processed before Content-Disposition under --etag-save. This flaw allows an HTTP(S) server to overwrite an existing local file specified in the Content-Disposition header despite the presence of the -J non-overwrite constraint.
