Improper Privilege Management in Cilium
Impact
If an attacker is able to perform a container escape of a container running as root on a host where Cilium is installed, the attacker can leverage Cilium's Kubernetes service account to gain access to cluster privileges that are more permissive than what is minimally required to operate Cilium. In affected releases, this service account had access to modify and delete Pod and Node resources.
Patches
The problem has been fixed and is available on versions >=1.9.16, >=1.10.11, >=1.11.5
Workarounds
There are no workarounds available.
Acknowledgements
The Cilium community has worked together with members of Isovalent, Amazon and Palo Alto Networks to prepare these mitigations. Special thanks to Micah Hausler (AWS), Robert Clark (AWS), Yuval Avrahami (Palo Alto Networks), and Shaul Ben Hai (Palo Alto Networks) for their cooperation.

Cilium is open source software for providing and securing network connectivity and loadbalancing between application workloads. Prior to versions 1.9.16, 1.10.11, and 1.11.15, if an attacker is able to perform a container escape of a container running as root on a host where Cilium is installed, the attacker can escalate privileges to cluster admin by using Cilium's Kubernetes service account. The problem has been fixed and the patch is available in versions 1.9.16, 1.10.11, and 1.11.5. There are no known workarounds available.
