Name of the Vulnerable Software and Affected Versions
Kubernetes (affected versions not specified)
Description
The issue is related to the possibility of bypassing the ImagePolicyWebhook admission plugin's policies when using ephemeral containers in Kubernetes clusters. This could allow a remote attacker to circumvent existing security restrictions when launching containers. The vulnerability is associated with the use of the ImagePolicyWebhook admission plugin together with ephemeral containers.
Recommendations
As a temporary workaround, consider disabling the use of ephemeral containers with the ImagePolicyWebhook admission plugin until a patch is available.
Restrict access to the ImagePolicyWebhook admission plugin to minimize the risk of exploitation.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
