Description
Withdrawn Advisory
This advisory has been withdrawn because the issue describes intended behavior and the output is not exposed to unauthorized users. This link has been maintained to preserve external references.
Original Description
An issue was discovered in Cloud Native Computing Foundation (CNCF) Helm. It displays values of secrets when the --dry-run flag is used. This is a security concern in some use cases, such as a --dry-run call by a CI/CD tool. NOTE: the vendor's position is that this behavior was introduced intentionally, and cannot be removed without breaking backwards compatibility (some users may be relying on these values).

Weakness
CWE-200: Exposure of Sensitive Information to an Unauthorized Actor
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
How to prevent it
- 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.
