EPSS

• CVE-2026-32750: 0.45% estimated exploitation activity in the next 30 days; percentile 39.01 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary POST /api/import/importStdMd passes the localPath parameter directly to model.ImportFromLocalPath with zero path validation. The function recursively reads every file under the given path and permanently stores their content as SiYuan note documents in the workspace database, making them searchable and accessible to all workspace users. Details File: kernel/api/import.go - function importStdMd model.ImportFromLocalPath (kernel/model/import.go:784): Unlike globalCopyFiles, there is no blocklist at all. Any readable path is accepted. The imported content is permanently stored in the workspace SQLite database and survives restarts. Chained attack with Bug #1 (renderSprig): Admin imports sensitive files -- content stored in blocks table -- non-admin user queries via querySQL through renderSprig. PoC Exploit: Impact An admin can permanently import the contents of any readable host directory into the workspace as searchable notes. Unlike globalCopyFiles, there is no blocklist -…

# Patch Next advisory brief: CVE-2026-32750

Advisory: SiYuan importStdMd: unvalidated localPath imports arbitrary host directories as persistent notes
IDs: CVE-2026-32750, GHSA-rjhh-m223-9qqv
Record: https://patchnext.com/advisories/cve-2026-32750 (revision 1, source checked 26 Oct 2026, 15:18 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.8)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/siyuan-note/siyuan: affected <= 0.0.0-20260313024916-fd6526133bb3

## Suggested inspection (read-only)
- Go github.com/siyuan-note/siyuan: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on github.com/siyuan-note/siyuan.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-rjhh-m223-9qqv (GitHub-reviewed advisory GHSA-rjhh-m223-9qqv lists affected ranges: Go github.com/siyuan-note/siyuan >=0 <=0.0.0-20260313024916-fd6526133bb3)
