CyberRota Analysis
AI-GeneratedThe vulnerability affects the SiYuan application prior to version 3.7.4, specifically the /api/filetree/authFilePublishAccess endpoint, which allows anonymous attackers to exploit information disclosure by sending requests with an empty password. This can lead to unauthorized confirmation of document existence across various access levels, including public, password-protected, and hidden or forbidden documents, ultimately resulting in potential exposure of sensitive information. Organizations using affected versions should prioritize patching to mitigate the risk of unauthorized access to confidential documents.

Original NVD Description
SiYuan before v3.7.4 contains an information disclosure vulnerability in the /api/filetree/authFilePublishAccess endpoint, which is registered with CheckAuth only and is reachable anonymously. The endpoint never sets a failure code, so its outcome is signalled entirely by the response message and by the presence of a Set-Cookie header, and these signals differ across access tiers. By submitting requests with an empty password for a candidate document identifier, an anonymous attacker can distinguish whether a document is public/nonexistent, password-protected, or exists at the hidden or forbidden tier, thereby confirming the existence of documents they are not permitted to access. Because hidden and forbidden entries store an empty password, such requests also cause the server to issue a publish-auth cookie for forbidden documents.
