Does this matter?

Lower severity and a low EPSS score (0.29%). Track it; it rarely justifies an emergency change on its own.

Description

SiYuan versions before v3.7.4 contain an information disclosure vulnerability in the UILayout filter that fails to properly restrict administrator workspace state from publish readers. Unauthenticated attackers can retrieve the administrator's open documents, search terms, notebook paths, and private asset locations by calling the getConf endpoint without authentication.
