CVE-2026-73042 [CRITICAL] – SiYuan before v3.7.4 fails to properly escape database menu metadata in HTML interpolation

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.
