{"id":"CVE-2026-72791","summary":"SiYuan v3.7.4-alpha.1 Information Disclosure via getAttributeViewFieldViews","details":"SiYuan v3.7.4-alpha.1 (a pre-release; the endpoint does not exist in stable v3.7.3 or earlier) contains an information disclosure vulnerability in the /api/av/getAttributeViewFieldViews endpoint. The route is registered with CheckAuth only and applies no publish-access filtering, so reader-role callers can retrieve the complete database view structure — every view's name, icon, layout type, and per-field Hidden flag — for any database whose avID is supplied, regardless of authorization. The issue was introduced by commit acfc02ee8 and fixed in v3.7.4-alpha.2.","aliases":["GHSA-57v5-wqx3-cgj4","GO-2026-6430"],"modified":"2026-10-31T02:47:49.524702983Z","published":"2026-08-12T19:07:39.634Z","database_specific":{"cwe_ids":["CWE-862"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72791.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72791.json"},{"type":"ADVISORY","url":"https://github.com/siyuan-note/siyuan/security/advisories/GHSA-57v5-wqx3-cgj4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72791"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/siyuan-before-information-disclosure-via-getattributeviewfieldviews"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/siyuan-note/siyuan","events":[{"introduced":"6f4c52a10fb8ba89056e78af9f7d19350c3fb4de"},{"fixed":"80b4afd810c16e78527920ae5c48785775706249"}],"database_specific":{"extracted_events":[{"source":"AFFECTED_FIELD","strategy":"StandardRange","range":[{"introduced":"3.7.4-alpha.1"},{"fixed":"3.7.4-alpha.2"}]},{"range":[{"introduced":"0"},{"fixed":"3.7.4-alpha.2"}],"source":"DESCRIPTION"}]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72791.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:L/SI:N/SA:N"}]}
