Waline is a comment system with backend support. In versions 3.15.2 and prior, @waline/client renders the comment editor's live preview with marked and no sanitizer (utils/markdown.ts), and the preview is injected with v-html. When a comment is edited, the editor is seeded with the comment's raw, un-sanitized body (orig). Only administrators and the comment owner can edit. So an administrator who clicks Edit on an attacker's comment renders that attacker's raw HTML in their own session: an unauthenticated commenter achieves privilege-escalation stored XSS against a moderator with a single Edit click. At time of publication, there are no publicly available patches.
