Summary

Duplicate Advisory: SiYuan: Full-content disclosure of publish-disabled documents via getHeading*Transaction endpoints (publish mode): reader-reachable rendered DOM with no publish-access check

Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-69mh-gvh4-8gp7. This link is maintained to preserve external references.

Original Description

SiYuan versions before v3.7.3 contain an information disclosure vulnerability in the getHeadingDeleteTransaction, getHeadingLevelTransaction, and getHeadingInsertTransaction endpoints that return rendered block DOM without publish-access checks. Anonymous readers or publish RoleReader tokens can supply a heading block ID to read full rendered content of publish-disabled documents that should be restricted.
