Upstream source description

LeafWiki is a self-hosted wiki. Prior to version 0.10.2, page titles returned by the search API could be rendered as raw HTML in the frontend. A user with editor or administrator permissions could create or modify a page title containing an HTML/JavaScript payload. When another user searched for a matching term, the payload could execute in the victim’s browser. The impact depends on deployment configuration. With `--public-access` enabled, unauthenticated visitors could be affected. In authenticated-only deployments, the issue could be used for cross-user XSS against logged-in users who can access search results. The issue has been fixed in version 0.10.2 by ensuring that author-controlled page titles in search results are not interpreted as raw HTML by the browser while preserving search result highlighting.
