Summary

## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-69mh-gvh4-8gp7.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.
