CyberRota Analysis
AI-GeneratedThe vulnerability affects SiYuan versions prior to 3.7.3, where the getBacklinkDoc and getBackmentionDoc content endpoints do not enforce proper access controls, allowing unauthorized users, including anonymous readers, to access sensitive document content. This could lead to the exposure of publish-forbidden documents and potentially allow attackers to exploit the system by determining document references. Organizations using affected versions of Oracle SiYuan should prioritize patching to mitigate the risk of unauthorized data exposure.

Original NVD Description
SiYuan before v3.7.3 fails to apply publish-access filters to the getBacklinkDoc and getBackmentionDoc content endpoints (/api/ref/getBacklinkDoc and /api/ref/getBackmentionDoc). While the corresponding backlink list endpoints filter publish-forbidden documents, the content endpoints (gated only by CheckAuth) do not. A publish-mode reader — including an anonymous reader when publish Basic Auth is disabled — can call these endpoints directly with a publish-forbidden document's ID to retrieve its rendered DOM content and to determine whether the document references a given block (a reference-existence oracle).
