Description

The node-cube package (prior to version 5.0.0) contains a vulnerability in its handling of prototype chain initialization, which could allow an attacker to inject properties into the prototype of built-in objects. This issue, categorized under CWE-1321, arises from improper validation of user-supplied input in the package's resource initialization process. Successful exploitation may lead to denial of service or arbitrary code execution in affected environments. The vulnerability affects versions up to and including 5.0.0-beta.19, and no official fix has been released to date.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for node-cube, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Remediation status

    The records we use list no patched version of node-cube for GHSA-8v65-5fw5-23wj. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.

  3. Mitigate without a patch

    Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
