The underlying weakness: Use of Cache Containing Sensitive Information
The code uses a cache that contains sensitive information, but the cache can be read by an actor outside of the intended control sphere.
How developers prevent this class of flaw
- Do not store unnecessarily sensitive information in the cache.
