Command injection in the NetBird desktop client (versions 0.60.0 through 0.74.6) lets a malicious or compromised peer inject arbitrary OpenSSH directives - including command-executing ones - into the system-wide drop-in config of other clients' Linux, macOS, Windows and FreeBSD hosts. Exploitation requires the attacker to control an enrolled peer whose crafted FQDN or hostname containing a double quote is distributed to the victim, and the injected command runs only when a local user subsequently invokes ssh, so peer membership plus a local user action are both prerequisites rather than an unauthenticated internet-facing attack. NetBird 0.74.7 fixes the issue by rejecting peer names that are not valid DNS names; no public exploit identified at time of analysis, and the Android and iOS apps are not affected.
