How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.
k8s.io/kubernetes Go → 1.27.16

Weakness
CWE-276: Incorrect Default Permissions
During installation, installed file permissions are set to allow anyone to modify those files.
How to prevent it
- Architecture and Design, Operation: The architecture needs to access and modification attributes for files to only those users who actually require those actions.
- Architecture and Design: Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
