Grav Admin before 2.0.20 Cross-Site Scripting via marked.js

Grav Admin before 2.0.20 fails to sanitize output from marked.parse() before injecting it into the DOM via Svelte's {@html} directive in MarkdownEditor and MarkdownModal components. Attackers can inject javascript: URI schemes in plugin or theme changelogs to execute arbitrary code in authenticated admin sessions without requiring site access.
