Description · from the CVE record

SiYuan before v3.7.4 stores attribute-view field names without HTML escaping and interpolates them directly into option elements via innerHTML in the sort menu. Attackers can inject markup by renaming a database field to execute arbitrary JavaScript when users open the sort menu, with Node integration enabled in the desktop client enabling code execution.
