Original description

VNote is a note-taking platform. Prior to 4.3.0, VNote uses the assignment `preNode.innerHTML = p_metaData` in src/data/extra/web/js/markdownit.js to insert YAML frontmatter metadata into a pre element before the protectFromXss sanitization path runs. Opening an attacker-supplied Markdown note can therefore execute stored JavaScript in the file:// viewer context. Because QWebEngineSettings::LocalContentCanAccessRemoteUrls enables local content to access remote URLs, the script can read reachable local note files and transmit their contents to a remote server without further interaction after the note is opened. This issue is fixed in version 4.3.0.
