Improper Input Validation

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.

All versions before 3.20.5, all versions starting from 3.21.0 before 3.21.5, all versions starting from 3.22.0 before 3.22.2

Upgrade to versions 3.21.5, 3.22.2, 3.20.5 or above.
