Name of the Vulnerable Software and Affected Versions
SiYuan versions prior to 3.7.3
Description
Stored and reflected cross-site scripting issues exist in SVG sanitization. Authenticated attackers can bypass the HTML parser-based cleaner by hiding script tags within
desc, style, or noscript elements. While the HTML parser treats these elements as raw text, browsers interpret them as executable SVG content when served as image/svg+xml, allowing script execution within the application origin.Recommendations
Update to version 3.7.3 or later.
