Name of the Vulnerable Software and Affected Versions SiYuan versions prior to 3.7.4

Description Stored Cross-Site Scripting (XSS) occurs because attribute-view field names are stored without HTML escaping and interpolated directly into option elements using innerHTML within the sort menu. An attacker can inject markup by renaming a database field, allowing the execution of arbitrary JavaScript when a user opens the sort menu. In the desktop client, if Node integration is enabled, this can lead to remote code execution.

Recommendations Update SiYuan to version 3.7.4 or later.
