Official 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.
