CVE-2022-39270: DiscoTOC is a Discourse theme component that generates a table of contents for topics. Users that can create topics in TOC-enabled categories (and have sufficient trust level - configured in component's settings) are able to inject arbitrary HTML on that topic's page.

Alternatively, admins can temporarily disable the DiscoTOC theme component.
