CVE-2021-31597
Description
A flaw was found in xmlhttprequest-ssl for Node.js. SSL certificate validation is disabled by default, due to rejectUnauthorized (when the property exists but is undefined) being considered to be false within the https.request function of Node.js (thus, no certificate is ever rejected). The highest threat from this vulnerablity is to data confidentiality and integrity as well as system availability.
Statement
The xmlhttprequest-ssl library is included in Red Hat Quay as a dependency of karma which is only used during testing. The library is not used a runtime reducing the impact of the vulnerability to low for Red Hat Quay.
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).
The following CVSS metrics and score provided are preliminary and subject to review.

Red Hat CVSS v3 Score Explanation
There are no any special restrictions or access conditions to being able to exploit this vulnerability, hence the Attack Complexity (AC) has been set to LOW. Because there is a potential impact to system availability the Availability (A) metric has been set to LOW.
Understanding the Weakness (CWE)
Integrity,Authentication
Technical Impact: Bypass Protection Mechanism; Gain Privileges or Assume Identity
When a certificate is invalid or malicious, it might allow an attacker to spoof a trusted entity by interfering in the communication path between the host and client. The product might connect to a malicious host while believing it is a trusted host, or the product might be deceived into accepting spoofed data that appears to originate from a trusted host.
