Technical description

Defuddle cleans up HTML pages. Prior to 0.19.1, site extractors interpolate page-derived image alt and src values, og:image values, and video descriptions into HTML strings without context-appropriate escaping, and buildExtractorResponse() returns this contentHtml without the main pipeline's DOM-based sanitization. The affected paths include src/extractors/x-article.ts, src/extractors/substack.ts, and src/extractors/youtube.ts. A malicious page or attacker-controlled content on a matching domain can inject event-handler attributes or javascript URLs that execute when a victim or downstream application renders the extracted HTML. This issue is fixed in version 0.19.1.

CVE-2026-53529—

———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.5h CVE-2026-534684.6 MED

———Typemill is a flat-file, Markdown-based content management system designed for informational documentation websites. Versions prior to 2.23.0 are vulnerable to stored HTML attribute injection in the page metadata fields (`og:title` and `og:description`). An authenticated user with permission to modify page metadata can inject arbitrary HTML attributes into generated `<meta>` tags due to missing output encoding. Under certain browser or DOM interaction scenarios, this may lead to stored cross-site scripting (XSS). Version 2.23.0 fixes the issue.5h CVE-2026-439806.3 MED

———Malla is a web analyzer for Meshtastic networks based on MQTT data. Prior to commit 4086e2b5f61615a813b70b25bc76095083552135, code names (long_name, short_name) received via MQTT are stored in SQLite without sanitization and rendered into the DOM without escaping. Any participant on a public Meshtastic MQTT broker can set a malicious node name that executes JavaScript in the browser of every Malla dashboard visitor. Commit 4086e2b5f61615a813b70b25bc76095083552135 fixes the issue.5h CVE-2026-332408.8 HIG
