IPv4 only clusters susceptible to MitM attacks via IPv6 rogue router advertisements

CVSS Rating: CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:L/I:L/A:L 6.0 Medium A cluster configured to use an affected container networking implementation is susceptible to man-in-the-middle MitM attacks. By sending “rogue” router advertisements, a malicious container can reconfigure the host to redirect...

Kubernetes: IPv4 only clusters susceptible to MitM attacks via IPv6 rogue router advertisements

This bug report mostly concerns the default CNI plugins https://github.com/containernetworking/plugins but I believe affects many K8S clusters. Because the CNI team still doesn’t provide an explicit way to report security bugs, I hope the K8S security team doesn’t mind doing the coordination job...
