CVE-2026-59832: Siyuan-Note Siyuan

High severity, CVSS 7.7. EPSS: 0.5% chance of exploitation in the next 30 days.

SiYuan is an open-source personal knowledge management system. Prior to 3.7.1, the /snippets/*filepath route handler serveSnippets in kernel/server/serve.go joins a single-decoded request path with the snippets directory without subpath containment or sensitive-path checks, allowing an authenticated request such as /snippets/%2e%2e/%2e%2e/conf/conf.json to read workspace secrets and the document database. This issue is fixed in versions 3.7.1.

Affected products

• Siyuan-Note Siyuan: before 3.7.1 (fixed in 3.7.1)
