Summary

Duplicate Advisory: Unauthenticated arbitrary SQL execution via searchEmbedBlock (publish mode) : reader-reachable raw statement on read-write handle, cross-notebook read/write

Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-vh22-h7hf-www7. This link is maintained to preserve external references.

Original Description

SiYuan versions <= v3.7.2 expose the /api/search/searchEmbedBlock endpoint, which passes a client-supplied SQL statement verbatim to the main read-write siyuan.db handle with no single-statement, read-only, or admin restrictions. The endpoint is gated only by CheckAuth, making it reachable by the publish RoleReader token and by anonymous users when publish authentication is disabled. Because the underlying driver executes stacked statements, an attacker can read and modify content across all opened cleartext notebooks (encrypted per-box notebooks are excluded). Fixed in v3.7.3.

Severity

10.0 (Critical)
