Note: Versions mentioned in the description apply only to the upstream kubeflow-pipelines-visualization-server package and not the kubeflow-pipelines-visualization-server package as distributed by Wolfi. See How to fix? for Wolfi relevant fixed versions and status.

Mistune is a Python Markdown parser with renderers and plugins. Prior to 3.2.1, HTMLRenderer.heading() builds the opening <hN> tag by string-concatenating the id attribute value directly into the HTML — with no call to escape(), safe_entity(), or any other sanitisation function. A double-quote character " in the id value terminates the attribute, allowing an attacker to inject arbitrary additional attributes (event handlers, src=, href=, etc.) into the heading element. This vulnerability is fixed in 3.2.1.
