CVE-2026-73605

Name of the Vulnerable Software and Affected Versions SiYuan versions prior to 3.7.4

Description A path traversal issue exists in the 'getUniqueFilename' endpoint.

This can be used to determine if specific files and directories exist on the host, facilitating reconnaissance of the filesystem layout and installed software.
