Duplicate Advisory: Missing publish-access check on getBlockBreadcrumb, getRefText, and getBlockTreeInfos discloses content and metadata of protected/forbidden documents

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-67x2-mq63-v9vm. This link is maintained to preserve external references.

Original Description

SiYuan versions before v3.7.4 fail to enforce publish-access checks on getBlockBreadcrumb, getRefText, and getBlockTreeInfos endpoints, allowing disclosure of protected document content and metadata. Anonymous readers or publish RoleReader accounts can retrieve document titles, ancestor block content snippets, reference text, and path metadata for publish-forbidden or password-protected documents by supplying block IDs.
