CVE-2026-73043

Name of the Vulnerable Software and Affected Versions SiYuan versions prior to 3.7.4

Description A remote code execution issue exists in the Template calculation operator. The software renders user-authored Go templates and stores the output without sanitization. This allows attackers to inject malicious HTML and JavaScript into template calculations. When the database is opened, these scripts execute in the desktop client renderer with Node integration enabled, leading to arbitrary code execution.

Recommendations Update SiYuan to version 3.7.4 or later.
