  "details": "Versions of `mem` prior to 4.0.0 are vulnerable to Denial of Service (DoS).  The package fails to remove old values from the cache even after a value passes its `maxAge` property. This may allow attackers to exhaust the system's memory if they are able to abuse the application logging.\n\n\n## Recommendation\n\nUpgrade to version 4.0.0 or later.",
