{"id":"GHSA-2qqv-3jgq-vpm9","summary":"Duplicate Advisory: Non-administrator responses from /api/system/getConf omit three secrets that the configuration-export path explicitly strips, disclosing the session-cookie signing key and the OS username to anonymous readers","details":"## Duplicate Advisory\n\nThis advisory has been withdrawn because it is a duplicate of GHSA-h4v5-crx2-3cv4. This link is maintained to preserve external references.\n\n## Original Description\nSiYuan versions before v3.7.4 fail to mask sensitive configuration fields in the /api/system/getConf endpoint, allowing anonymous or publish-reader users to obtain the session-cookie signing key, OS username via pandoc path, and encrypted-notebook key material. Attackers can forge and tamper with session cookies to impersonate users, and on instances without access-auth codes configured, escalate to administrator privileges.","modified":"2026-09-04T21:30:06.459600173Z","published":"2026-08-12T21:31:41Z","withdrawn":"2026-09-04T21:16:30Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2026-09-04T21:16:30Z","nvd_published_at":"2026-08-12T20:17:50Z","cwe_ids":["CWE-522"],"severity":"CRITICAL"},"references":[{"type":"WEB","url":"https://github.com/siyuan-note/siyuan/security/advisories/GHSA-h4v5-crx2-3cv4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72793"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/siyuan-before-information-disclosure-via-api-system-getconf"}],"affected":[{"package":{"name":"github.com/siyuan-note/siyuan/kernel","ecosystem":"Go","purl":"pkg:golang/github.com/siyuan-note/siyuan/kernel"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"last_affected":"3.7.3"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/08/GHSA-2qqv-3jgq-vpm9/GHSA-2qqv-3jgq-vpm9.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
