Description
Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-hf8h-97gm-4x2p. This link is maintained to preserve external references.
Original Description
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.
