    CVE-2026-104078 (GCVE-0-2026-104078)

    Vulnerability from nvd – Published: 2026-10-08 16:38 – Updated: 2026-10-08 17:58

    Title
    Obsidian Desktop < 1.14.0 RCE via MathJax Safe Filter Bypass
    Summary
    Obsidian Desktop before 1.14.0 contains a filter bypass vulnerability in the bundled MathJax 3.2.2 Safe component that allows attackers to execute arbitrary code by embedding a crafted \href value with a TAB byte in the URL scheme, causing filterURL to produce an empty protocol that bypasses the configured safeProtocols restrictions. Attackers can craft a note containing a malicious MathJax formula that renders as a javascript: URL anchor, which when clicked by the victim in Live Preview executes in the Node-integration-enabled vault renderer via require('child_process'), achieving arbitrary operating system command execution as the desktop user.

    CVE-2026-104077 (GCVE-0-2026-104077)

    Vulnerability from nvd – Published: 2026-10-08 16:27 – Updated: 2026-10-08 17:14
    VLAI
    Title
    Obsidian Desktop < 1.14.0 RCE via Slides Plugin Markdown
    Summary
    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.

    CVE-2026-104078 (GCVE-0-2026-104078)

    Vulnerability from cvelistv5 – Published: 2026-10-08 16:38 – Updated: 2026-10-08 17:58

    Title
    Obsidian Desktop < 1.14.0 RCE via MathJax Safe Filter Bypass
    Summary
    Obsidian Desktop before 1.14.0 contains a filter bypass vulnerability in the bundled MathJax 3.2.2 Safe component that allows attackers to execute arbitrary code by embedding a crafted \href value with a TAB byte in the URL scheme, causing filterURL to produce an empty protocol that bypasses the configured safeProtocols restrictions. Attackers can craft a note containing a malicious MathJax formula that renders as a javascript: URL anchor, which when clicked by the victim in Live Preview executes in the Node-integration-enabled vault renderer via require('child_process'), achieving arbitrary operating system command execution as the desktop user.

    CVE-2026-104077 (GCVE-0-2026-104077)

    Vulnerability from cvelistv5 – Published: 2026-10-08 16:27 – Updated: 2026-10-08 17:14

    Title
    Obsidian Desktop < 1.14.0 RCE via Slides Plugin Markdown
    Summary
    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.
