CyberRota Analysis
AI-GeneratedThe vulnerability affects SiYuan versions prior to 3.7.2, allowing for stored cross-site scripting (XSS) through unescaped HTML in database cell rendering. This flaw enables attackers to inject malicious scripts that can execute arbitrary commands due to the enabled nodeIntegration in the desktop renderer. Organizations using SiYuan should prioritize patching this vulnerability to mitigate the risk of severe exploitation.

Original NVD Description
SiYuan before v3.7.2 contains a stored cross-site scripting vulnerability in Attribute View (database) cell rendering. A Template column value is rendered as HTML via text/template without auto-escaping, and EscapeHTML is only applied when HasUnclosedHtmlTag returns true; because balanced self-closing tags such as <img> are skipped by that check, a payload like <img src=x onerror=...> is stored unescaped and later inserted into the page via innerHTML, executing when the database is viewed. Because the desktop renderer runs with nodeIntegration enabled, the injected script can reach require and escalate to arbitrary command execution.
