NVD Description

Note: Versions mentioned in the description apply only to the upstream openshift4/ose-console package and not the openshift4/ose-console package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

showdown contains a stored cross-site scripting vulnerability in the parseHeaders function of src/subParsers/makehtml/tables.js that fails to properly escape table header ID attributes. Attackers can inject arbitrary HTML and script-executing SVG elements through double-quote characters in markdown table headers, achieving stored XSS when untrusted markdown is rendered with the default github flavor configuration.
