CVE-2025-10966  (opens in a new tab)

How to fix?

Upgrade Alpine:3.24 curl to version 8.17.0-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.

curl's code for managing SSH connections when SFTP was done using the wolfSSH powered backend was flawed and missed host verification mechanisms.

This prevents curl from detecting MITM attackers and more.
