Calico vulnerable to pod route hijacking
Quick fix
GHSA-9394-xfq9-6qrp — github.com/projectcalico/calico: upgrade to the fixed version with the command below.
go get github.com/projectcalico/calico@v3.22.2Details
Clusters using Calico (version 3.22.1 and below), Calico Enterprise (version 3.12.0 and below), may be vulnerable to route hijacking with the floating IP feature. Due to insufficient validation, a privileged attacker may be able to set a floating IP annotation to a pod even if the feature is not enabled. This may allow the attacker to intercept and reroute traffic to their compromised pod.
