This could lead to the exposure of sensitive information, including database names and document paths. Organizations using affected versions should prioritize patching to mitigate potential data leaks.

Original NVD Description

SiYuan versions before v3.7.4 contain an information disclosure vulnerability in the getAttributeViewBacklinks endpoint that consults the forbidden access list instead of the visibility list when filtering backlinks. Anonymous readers can supply a publicly visible database row identifier to discover hidden-tier documents that reference it, receiving the database name, row title, and document path of hidden documents.
