This advisory has been withdrawn because it is a duplicate of GHSA-c8r8-95hg-mp34. This link is maintained to preserve external references.
SiYuan versions before v3.8.0 contain an incomplete path blocklist in the MCP file tool that fails to restrict access to sensitive workspace files protected by the HTTP API. Authenticated administrators can read plaintext publish-mode passwords from data/.siyuan/publishAccess.json and access other sensitive files like data/templates and data/snippets/conf.json.
