How to fix?

Upgrade Echo:latest curl to version 1:8.23.0-1+e1 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 Echo. See How to fix? for Echo:latest relevant fixed versions and status.

When CURLOPT_INTERFACE (or the command line tool's --interface option) is set with one of the documented prefixes (if!, host!, ifhost!), that binding is not part of the connection reuse key, so a later transfer asking for a different source can silently reuse an existing connection and go out from the earlier transfer's source address
