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.

Weakness
CWE-524: 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 to prevent it
- Architecture and Design: Protect information stored in cache.
- Architecture and Design: Do not store unnecessarily sensitive information in the cache.
- Architecture and Design: Consider using encryption in the cache.
