CVE-2026-104078
7.8 ÉlevéeDescription
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.
