Contrast (edgelesssys\/contrast) versions 1.14.0 before 1.23.1 generate runtime policies that fail to detect all container image substitutions. A bad rebase during a Kata Containers update accidentally introduced an `allow_storage` rule that accepts storage entries using the `image_guest_pull` driver without verifying the image digest. An attacker with access to the Kata agent API \u2014 for example, a Kubernetes cluster administrator in Contrast’s threat model \u2014 can therefore substitute a container image with an exploit payload, provided the substituted image satisfies the remaining policy rules, undermining the confidential container’s integrity guarantees.<\/p>\n","protected":false},"excerpt":{"rendered":"
