CVE-2026-73044
CriticalCVSS 9.0Summary
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.
Risk Assessment
An attacker can execute arbitrary code in the Electron renderer, potentially leading to full system compromise, data theft, or malware installation.
Recommendation
Update SiYuan to version v3.7.4 or later, which includes a fix for validation and escaping of table column width values.
