CVE-2020-15366
Description
A flaw was found in nodejs-ajv. A carefully crafted JSON schema could be provided that allows execution of other code by prototype pollution. While untrusted schemas are recommended against, the worst case of an untrusted schema should be a denial of service, not execution of code.
Statement
In both OpenShift Container Platform (OCP) and OpenShift ServiceMesh (OSSM), the affected containers are behind OpenShift OAuth authentication. This restricts access to the vulnerable nodejs-ajv library to authenticated users only, therefore the impact is low.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
