Fission versions prior to 1.24.0 contain a critical vulnerability in the Container Executor path that allows a tenant with only functions.fission.io/create permission to escalate privileges and escape the node. This occurs because the Function.spec.podspec field was not properly validated, allowing malicious pod specifications that mount the host root filesystem and share host namespaces. The executor merges these unsafe podspecs into deployments running with high privileges, enabling node escape. The issue is fixed in version 1.24.0 by adding strict validation and sanitization of podspec fields that could lead to privilege escalation or host access.
