Denial of Service in mem

Moderate severity GitHub Reviewed Published Jul 5, 2019 to the GitHub Advisory Database • Updated Jan 9, 2023

Package

npm mem (npm)

Affected versions

< 4.0.0

Patched versions

4.0.0

Description

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.

Recommendation

Upgrade to version 4.0.0 or later.
