Description
Obsidian Desktop before 1.14.0 contains a remote code execution vulnerability that allows attackers to craft malicious Markdown notes exploiting insufficient sanitization of the data-background-iframe attribute, which bypasses DOMPurify and is processed by the bundled Reveal.js 4.3.1 within the Slides core plugin, allowing a javascript: URL to execute in the resulting background iframe. Because Node integration is enabled and context isolation is disabled in Obsidian's vault renderer, the injected script can call parent.require() to access Node APIs such as fs and child_process, enabling arbitrary operating system command execution when the victim opens the note and manually starts the presentation.
