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.","published":"2026-03-20T00:13:31.384Z","modified":"2026-08-07T11:48:53.233731892Z","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/siyuan-note/siyuan/kernel","fixedVersion":null}],"fix":{"url":"https://github.com/siyuan-note/siyuan/commit/d5e2d0bce0dffef5f61bd8066954bc2d41181fc5","label":"siyuan-note/siyuan@d5e2d0b"},"references":[{"type":"WEB","url":"https://github.com/siyuan-note/siyuan/releases/tag/v3.6.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32767.json"},{"type":"ADVISORY","url":"https://github.com/siyuan-note/siyuan/security/advisories/GHSA-j7wh-x834-p3r7"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32767"},{"type":"REPORT","url":"https://github.com/siyuan-note/siyuan/issues/17209"},{"type":"FIX","url":"https://github.com/siyuan-note/siyuan/commit/d5e2d0bce0dffef5f61bd8066954bc2d41181fc5"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:48:53.233731892Z"}}
