CVE-2026-73050

SiYuan versions before v3.7.4 fail to validate or escape the color field in attribute-view select options, allowing stored cross-site scripting through eight unescaped render sites. Attackers can inject event-handler attributes by including quotation marks in the color value, executing arbitrary JavaScript when viewing databases containing the malicious select field.
