CVE-2026-73044
SiYuan versions before v3.7.4 fail to validate or escape table column width values, allowing stored cross-site scripting injection into style attributes.
Impact
SiYuan versions before v3.7.4 fail to validate or escape table column width values, allowing stored cross-site scripting injection into style attributes. Attackers can inject malicious payloads through the setAttrViewColWidth API that break out of style attributes and inject event handlers on every table cell, executing arbitrary code in the Electron renderer with Node integration enabled.
