https://notcve.org/view.php?id=CVE-2022-46180
Discourse Mermaid (discourse-mermaid-theme-component) allows users of Discourse, open-source forum software, to create graphs using the Mermaid syntax. Users of discourse-mermaid-theme-component version 1.0.0 who can create posts are able to inject arbitrary HTML on that post. The issue has been fixed on the `main` branch of the GitHub repository, with 1.1.0 named as a patched version. Admins can update the theme component through the admin UI. As a workaround, admins can temporarily disable discourse-mermaid-theme-component. • https://github.com/discourse/discourse-mermaid-theme-component/commit/c10bc4a08bf865cee20e5d5dffba535762813f0f https://github.com/discourse/discourse-mermaid-theme-component/pull/14 https://github.com/discourse/discourse-mermaid-theme-component/security/advisories/GHSA-8437-hgcm-p3q3 • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
