Does this matter?

Lower severity and a low EPSS score (0.24%). 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 getEncryptedNotebookStatus endpoint that returns encrypted notebook identifiers, names, and lock states without publish-access filtering. Anonymous readers and publish-mode accounts can enumerate all encrypted notebooks and their current unlock status, revealing sensitive notebook names and decryption state in memory.
