CVE-2021-44906

An Uncontrolled Resource Consumption flaw was found in minimist. The original fix for CVE-2020-7598 was incomplete as it was still possible to bypass in some cases. This flaw (CVE-2021-44906) allows an attacker to trick the library into adding or modifying the properties of Object.prototype, using a constructor or proto payload, resulting in prototype pollution and loss of confidentiality, availability, and integrity.

As minimist is an argument parsing module for nodejs, exploitation of this vulnerability requires an attacker to influence which arguments are passed to nodejs when running a script. Red Hat products and services are designed in such a way that gaining this ability is not trivial. Additionally, the impact is limited by only enabling the pollution of functions, and not all generic objects.

Within Red Hat Satellite 6 this flaw has been rated as having a security impact of Low. It is not currently planned to be addressed there, as the minimist library is only included in the -doc subpackage and is part of test fixtures that are not in the execution path used by the rabl gem.
