Description
Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-5w7r-f4cg-rqq7. This link is maintained to preserve external references.
Original Description
SiYuan before v3.7.4 (affected <=v3.7.2) fails to enforce publish-access filters on five filetree path-resolution endpoints (getFullHPathByID, getHPathByID, getPathByID, getIDsByHPath, and getHPathByPath). In publish mode, when Publish.Auth.Enable is false, an unauthenticated (anonymous) reader — or any publish reader token — can call these endpoints to enumerate the complete private document tree, mapping notebook names, folder hierarchies, and document titles, and resolving title paths to document IDs, including for documents marked hidden, password-protected, or publish-forbidden.

Weakness
CWE-862: Missing Authorization
The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
How to prevent it
- Architecture and Design: Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) [REF-229] to enforce the roles at the appropriate boundaries. Note that this approach may not protect against horizontal authorization, i.e., it will not protect a user from attacking others with the same role.
- Architecture and Design: Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records. For example, a database may restrict access for medical records to a specific database user, but each record might only be intended to be accessible to the patient and the patient's doctor [REF-7].
- Architecture and Design: Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. For example, consider using authorization frameworks such as the JAAS Authorization Framework [REF-233] and the OWASP ESAPI Access Control feature [REF-45].
- Architecture and Design: For web applications, make sure that the access control mechanism is enforced correctly at the server side on every page. Users should not be able to access any unauthorized functionality or information by simply requesting direct access to that page. One way to do this is to ensure that all pages containing sensitive information are not cached, and that all such pages restrict access to requests that are accompanied by an active and authenticated session token associated with a user who has the required permissions to access that page.
- System Configuration, Installation: Use the access control capabilities of your operating system and server environment and define your access control lists accordingly. Use a "default deny" policy when defining these ACLs.
