Details

As written in the advisory (Markdown source, shown as plain text).

### Impact Due to a mis-written NetworkPolicy, a malicious actor can pivot from the "hardened" namespace to any Pod out of it. This breaks the security-by-default property expected as part of the deployment program, leading to a potential lateral movement. ### Patch Removing the `inter-ns` NetworkPolicy patches the vulnerability. If updates are not possible in production environments, we recommend to manually delete it and update as soon as possible. ### Workaround Given your context, delete the failing network policy that should be prefixed by `inter-ns-` in the target namespace.
