SiYuan: The reference filter for getRefIDs checks visibility but not the password tier, disclosing that password-protected documents reference a given block
GitHub lists this reviewed advisory for github.com/siyuan-note/siyuan/kernel. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.
01 / Meaning
Why it matters
Published affected context helps an owner decide what evidence to gather. This report has not examined your application.
5.8 medium
GitHub source severity; exploitability and local consequence require separate evidence.

### Summary `/api/block/getRefIDs` filters its results for reader roles through a helper that checks only the visibility tiers. The password tier is not checked, because the helper does not receive the request context and therefore cannot evaluate the publish auth cookie. A reader who has not entered a document's publish password learns that the document references a given block. A function ten lines away in the same file does perform the full check, on the same input type. ### Details **Route,** identical at `eef105683` (`kernel/api/router.go:235`) and dev `a7ae96ce` (`:245`): ```go ginServer.Handle("POST", "/api/block/getRefIDs", model.CheckAuth, getRefIDs) ``` No `CheckReadonly`, no `CheckAdminRole`. **The filter chain.** `getRefIDs` (`kernel/api/block.go:631`) checks `isEncryptedNotebookDeniedForPublish`, calls `model.GetBlockRefsInBox`, then for read-only roles: ```go publishIgnore := model.GetInvisiblePublishAccess(publishAccess) refDefs, originalRefBlockIDs = model.FilterRefDefsByPublishIgnore(publishIgnore, refDefs) ``` `FilterRefDefsByPublishIgnore` (`kernel/model/publish_access.go:1324`) collects the reference and definition identifiers, resolves their block tree
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.
05 / Provenance
Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
