CVE-2026-73042

SiYuan before v3.7.4 fails to properly escape database menu metadata in HTML interpolation, allowing stored values to execute script when users open group, view, or field-edit menus. Attackers can inject markup through field descriptions or names that close containing elements and execute arbitrary code via event handlers, reaching Node built-ins due to Electron's insecure configuration.
