SiYuan 3.8.7 through 3.8.8 Path Traversal via GLOBALROOT Alias
Summary
SiYuan 3.8.7 through 3.8.8 fails to normalize Windows GLOBALROOT device-namespace aliases, bypassing the IsSensitivePath denylist. Attackers can invoke importStdMd with a GLOBALROOT-prefixed path to copy the API token and TLS private key into the publicly served assets directory.

Title
SiYuan 3.5.4 before 3.8.7 Sensitive Path Bypass via Windows Extended-Length Prefix
Summary
SiYuan 3.5.4 before 3.8.7 on Windows contains a sensitive-path denylist bypass in IsSensitivePath because the Windows extended-length prefix (\\?\) survives filepath.Clean and matches no forbidden prefix. Authenticated API callers can prepend the prefix to localPath in /api/import/importStdMd to copy workspace conf files, including the API token and TLS private keys, into assets served to unauthenticated clients.

Title
SiYuan before v3.8.7 Path Traversal Local File Read via MCP Asset Tool
Summary
SiYuan before 3.8.7 contains a path traversal vulnerability in the MCP asset tool because validateAssetUploadPaths relies on an incomplete sensitive-path blacklist that omits .env and other secret files. Authenticated attackers driving the MCP asset upload action can copy such local files into the workspace and read them back via /assets/ over HTTP.

6.2 (Medium)

SiYuan 2.9.0 before 3.8.7 XSS via check-auth to Parameter
Summary
SiYuan from 2.9.0 before 3.8.7 contains a cross-site scripting vulnerability in the unauthenticated /check-auth page that assigns the to parameter to window.location.href without scheme validation. Attackers can send a crafted link with a javascript: URI that executes after victim login, invoking kernel APIs to read or modify workspace content and settings.

SiYuan 3.6.0 before 3.8.7 Cleartext Transmission via Unenforced networkServeTLS Setting
Summary
SiYuan 3.6.0 before 3.8.7 accepts and persists the networkServeTLS setting but never enforces it, so the kernel port keeps serving full API access over plain HTTP alongside HTTPS. Network-adjacent attackers can sniff the cleartext login flow and session cookie, which lacks the Secure attribute while responses omit HSTS, to hijack kernel API sessions.

Title
SiYuan v3.7.0 before v3.8.6 Arbitrary File Read via Plugin ResponseFile.Path
Summary
SiYuan v3.7.0 before v3.8.6 contains an absolute path traversal vulnerability in the kernel's private plugin HTTP server, which passes a kernel plugin handler's ResponseFile.Path to gin's Context.File without validation. Attackers supplying a malicious kernel plugin can return an absolute path to read any file readable by the SiYuan process, including the API token and conf.json.

Title
SiYuan before 3.8.5 Information Disclosure via /api/block/getDocInfo and getDocsInfo
Summary
SiYuan before 3.8.5 contains an information disclosure vulnerability that allows publish-mode readers to learn backlink block IDs and reference counts from password-protected and publish-disabled documents by querying a published document. Attackers can send POST requests to /api/block/getDocInfo or getDocsInfo for a published document ID to obtain refIDs and refCount of hidden referencing blocks, bypassing the publish confidentiality boundary.

Title
SiYuan before v3.8.5 Information Disclosure via /api/notebook/getNotebookInfo
Summary
SiYuan before v3.8.5 contains an information disclosure vulnerability that allows read-only publish readers to learn metadata of publish-excluded documents through the getNotebookInfo endpoint. Attackers, including anonymous visitors when no reader password is set, can query publish-visible notebooks to obtain document count, size and modification timestamps of hidden documents.

Title
SiYuan before v3.8.5 Missing Authorization in Save-Path Resolver Endpoints
Summary
SiYuan before v3.8.5 contains a missing authorization vulnerability in the getRefCreateSavePath, getShorthandSavePath, and getDocCreateSavePath endpoints that allows read-only publish visitors to learn unpublished notebook box IDs. Attackers with read-only or anonymous publish access can POST any open notebook ID to receive the global save-box ID and save-path template, revealing a hidden notebook's existence and creation time.

SiYuan before v3.8.4 Information Disclosure via getCurrentAttrViewImages
Summary
SiYuan before v3.8.4 fails to enforce publish-access checks in the getCurrentAttrViewImages endpoint, allowing publish readers to retrieve image asset paths from unauthorized databases. Attackers can call the endpoint with an unrendered database identifier obtained through related endpoints to leak detached-row image asset paths and filenames that the rendering endpoint would deny.

Title
SiYuan 3.5.4 before 3.8.7 Sensitive Path Bypass via Windows Extended-Length Prefix
Summary
SiYuan 3.5.4 before 3.8.7 on Windows contains a sensitive-path denylist bypass in IsSensitivePath because the Windows extended-length prefix (\\?\) survives filepath.Clean and matches no forbidden prefix. Authenticated API callers can prepend the prefix to localPath in /api/import/importStdMd to copy workspace conf files, including the API token and TLS private keys, into assets served to unauthenticated clients.

Title
SiYuan before v3.8.7 Path Traversal Local File Read via MCP Asset Tool
Summary
SiYuan before 3.8.7 contains a path traversal vulnerability in the MCP asset tool because validateAssetUploadPaths relies on an incomplete sensitive-path blacklist that omits .env and other secret files. Authenticated attackers driving the MCP asset upload action can copy such local files into the workspace and read them back via /assets/ over HTTP.

Title
SiYuan 3.6.0 before 3.8.7 Cleartext Transmission via Unenforced networkServeTLS Setting
Summary
SiYuan 3.6.0 before 3.8.7 accepts and persists the networkServeTLS setting but never enforces it, so the kernel port keeps serving full API access over plain HTTP alongside HTTPS. Network-adjacent attackers can sniff the cleartext login flow and session cookie, which lacks the Secure attribute while responses omit HSTS, to hijack kernel API sessions.

SiYuan v3.7.0 before v3.8.6 Arbitrary File Read via Plugin ResponseFile.Path
Summary
SiYuan v3.7.0 before v3.8.6 contains an absolute path traversal vulnerability in the kernel's private plugin HTTP server, which passes a kernel plugin handler's ResponseFile.Path to gin's Context.File without validation. Attackers supplying a malicious kernel plugin can return an absolute path to read any file readable by the SiYuan process, including the API token and conf.json.

Title
SiYuan before 3.8.5 Information Disclosure via /api/block/getDocInfo and getDocsInfo
Summary
SiYuan before 3.8.5 contains an information disclosure vulnerability that allows publish-mode readers to learn backlink block IDs and reference counts from password-protected and publish-disabled documents by querying a published document. Attackers can send POST requests to /api/block/getDocInfo or getDocsInfo for a published document ID to obtain refIDs and refCount of hidden referencing blocks, bypassing the publish confidentiality boundary.

Title
SiYuan before v3.8.5 Missing Authorization in Save-Path Resolver Endpoints
Summary
SiYuan before v3.8.5 contains a missing authorization vulnerability in the getRefCreateSavePath, getShorthandSavePath, and getDocCreateSavePath endpoints that allows read-only publish visitors to learn unpublished notebook box IDs. Attackers with read-only or anonymous publish access can POST any open notebook ID to receive the global save-box ID and save-path template, revealing a hidden notebook's existence and creation time.

Title
SiYuan before v3.8.4 Information Disclosure via getCurrentAttrViewImages
Summary
SiYuan before v3.8.4 fails to enforce publish-access checks in the getCurrentAttrViewImages endpoint, allowing publish readers to retrieve image asset paths from unauthorized databases. Attackers can call the endpoint with an unrendered database identifier obtained through related endpoints to leak detached-row image asset paths and filenames that the rendering endpoint would deny.
