CVE-2026-32767
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedSiYuan is a personal knowledge management system. Versions 3.6.0 and below contain an authorization bypass vulnerability in the /api/search/fullTextSearchBlock endpoint. When the method parameter is set to 2, the endpoint passes user-supplied input directly as a raw SQL statement to the underlying SQLite database without any authorization or read-only checks. This allows any authenticated user — including those with the Reader role — to execute arbitrary SQL statements (SELECT, DELETE, UPDATE, DROP TABLE, etc.) against the application's database. This is inconsistent with the application's own security model: the dedicated SQL endpoint (/api/query/sql) correctly requires both CheckAdminRole and CheckReadonly middleware, but the search endpoint bypasses these controls entirely. This issue has been fixed in version 3.6.1.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceSiYuan versions 3.6.0 and below contain an authorization bypass in /api/search/fullTextSearchBlock where setting the method parameter to 2 passes user input directly as raw SQL to SQLite without CheckAdminRole or CheckReadonly middleware checks, allowing any authenticated user to execute arbitrary SQL statements including DELETE, UPDATE, and DROP TABLE operations.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify SiYuan installation versionCheck the application version displayed in the SiYuan desktop or web interface, or examine the version information in the installation directory or package metadataAffected if the installed version is 3.6.0 or lower (any version below 3.6.1)
-
Verify the application is runningConfirm the SiYuan application is active and accessible via its web interface or desktop clientAffected if the application is running and accepting connections
-
Confirm authentication is enabledCheck whether user authentication is configured and active in the SiYuan instanceAffected if any authenticated user account exists in the system (the vulnerability affects any authenticated user, not just administrators)
-
Assess network exposure of the API endpointDetermine if the /api/search/fullTextSearchBlock endpoint is reachable from the network where attackers could send requestsAffected if the API endpoint is accessible over the network to authenticated users
You are affected if SiYuan version 3.6.0 or below is running and the application accepts authenticated user connections, since the vulnerable endpoint accepts method=2 to bypass authorization and execute raw SQL.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped3.6.1
Upgrade to SiYuan version 3.6.1 or later, which includes the proper authorization and read-only middleware checks that were missing from the vulnerable endpoint.
3.6.1
- Upgrade SiYuan to version 3.6.1 or later from the official release page or package manager
- After upgrading, verify that the /api/search/fullTextSearchBlock endpoint no longer accepts method=2 with arbitrary SQL
- Confirm the application functions normally after the upgrade
