Upgrade github.com/ctfer-io/monitoring to 0.2.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

inspect dependencies for github.com/ctfer-io/monitoring

How to Check if You Are Affected

To determine whether your application is affected by CVE-2026-32720, inspect your project dependencies for Github.com/ctfer io/monitoring:

inspect dependencies for github.com/ctfer-io/monitoring

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-284: Improper Access Control, where the product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. In Github.com/ctfer io/monitoring, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact Due to a mis-written NetworkPolicy, a malicious actor can pivot from a component to any other namespace. 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 monitoring namespace. You can use the following to delete all matching network policy. If unsure of the outcome, please do it manually. ```bash for ns in $(kubectl get ns -o jsonpath='{.items[*].metadata.name}' | tr ' ' '\n' | grep '^monitoring-'); do kubectl -n "$ns" get networkpolicy -o name \ | grep '^networkpolicy.networking.k8s.io/inter-ns-' \ | xargs -r kubectl -n "$ns" delete done ```
