How to fix?

Upgrade Echo:latest curl to version 8.14.0 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.

libcurl accidentally skips the certificate verification for QUIC connections when connecting to a host specified as an IP address in the URL. Therefore, it does not detect impostors or man-in-the-middle attacks.
