CVE-2022-28224: Tigera Calico

Medium severity, CVSS 5.5. EPSS: 0.6% chance of exploitation in the next 30 days.

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.

Affected products

• Tigera Calico: before 3.20.5 (fixed in 3.20.5); from 3.21.0, before 3.21.5 (fixed in 3.21.5); from 3.22.0, before 3.22.2 (fixed in 3.22.2)
• Tigera Calico Enterprise: before 3.11.4 (fixed in 3.11.4); version 3.12.0 only
