CVE-2026-32704: SiYuan renderSprig: missing admin check allows any user to read full workspace DB

Noroxi assessment

Priority: Monitor (action score 26/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.26% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: siyuan-note siyuan 3.6.1.

Low priority for now. Upgrade to siyuan-note siyuan 3.6.1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

SiYuan is a personal knowledge management system. Prior to 3.6.1, POST /api/template/renderSprig lacks model.CheckAdminRole, allowing any authenticated user to execute arbitrary SQL queries against the SiYuan workspace database and exfiltrate all note content, metadata, and custom attributes. This vulnerability is fixed in 3.6.1.
