Technical description

SiYuan's development branch (endpoint introduced by commit 9b8e8956f, not present in v3.7.3 or master, patched in v3.7.4) contains a missing-authorization vulnerability in the /api/av/getAttributeViewSearchTarget endpoint. The route is registered with CheckAuth only and performs no authorization checks (no CheckReadonly, no publish-access or encrypted-notebook gating). Given a database identifier taken from a published page and a keyword, an anonymous reader can query the endpoint to retrieve matching database row content, including rows that publish filters (FilterAttributeViewByPublishAccess) would otherwise withhold. No released stable version is affected.

———SiYuan versions before v3.7.4 contain an information disclosure vulnerability in the getBookmarkLabels endpoint that returns all bookmark labels in the workspace without publish-access filtering. Anonymous readers and publish-mode readers can obtain the complete bookmark vocabulary across the workspace, disclosing subject matter and organizational information from inaccessible documents.13h CVE-2026-736075.8 MED

———SiYuan versions before v3.7.4 contain a path traversal vulnerability in the getUniqueFilename endpoint that allows anonymous readers to probe filesystem existence without validation or confinement. Attackers can supply arbitrary absolute paths to determine whether files and directories exist on the host, enabling reconnaissance of the filesystem layout and installed software.13h CVE-2026-73603—

——0UpSnap is a wake on lan web app. Versions 4.4.1 through 5.3.5 are vulnerable to a missing-authentication / privilege-escalation chain in `pb.HandlerInitSuperuser` (`backend/pb/handlers.go:249`), reachable as `POST /api/upsnap/init-superuser`. The vulnerable code lacks any authentication, setup token, IP allow-list, or rate limit and is gated only by a `totalSuperusers > 0` count check — a condition that is false on every fresh install — allowing an unauthenticated network-adjacent attacker to register the initial superuser account, receive a long-lived JWT, and pivot to root remote code execution at `backend/networking/wake.go:43` (`exec.CommandContext(ctx, "/bin/sh", "-c", wake_cmd)`). Version 5.4.0 fixes the issue.12h
