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.

SiYuan: getEncryptedNotebookStatus discloses names and current lock/unlock state of all encrypted notebooks to anonymous readers
**CVE:** This vulnerability corresponds to [CVE-2026-72797](https://nvd.nist.gov/vuln/detail/CVE-2026-72797).
### Summary
`POST /api/notebook/getEncryptedNotebookStatus` returns the identifier, name, and current lock state of every encrypted notebook, with no publish-access filtering. The route is registered `CheckAuth` only, no `CheckReadonly`, no `CheckAdminRole` so it is reachable by the publish `RoleReader` token and by the anonymous account when `Publish.Auth.Enable` is `false`. Encrypted notebooks are private by design; their names frequently reveal the sensitive topic that motivated encrypting them.
### Details
