CVE-2025-23390 · Fleet doesn’t validate a server’s certificate when connecting through SSH
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
A vulnerability has been identified within Fleet where, by default, Fleet will automatically trust a remote server’s certificate when connecting through SSH if the certificate isn’t set in the `known_hosts` file. This could allow the execution of a man-in-the-middle (MitM) attack against Fleet. In case the server that is being connected to has a trusted entry in the known_hosts file, then Fleet will correctly check the authenticity of the presented certificate.
