{"id":"CVE-2026-54068","aliases":["GHSA-gcm7-57gf-953c","GO-2026-5958"],"url":"https://o3.security/vulnerability/CVE-2026-54068","summary":"SiYuan: Unauthenticated SQLite Data Exfiltration via Template Injection in /api/icon/getDynamicIcon","details":"SiYuan is an open-source personal knowledge management system. Prior to 3.7.0, the /api/icon/getDynamicIcon endpoint is explicitly excluded from authentication in SiYuan's kernel router (router.go, \"不需要鉴权\" -- no auth needed). When called with type=8 and a valid block id parameter, this endpoint invokes RenderDynamicIconContentTemplate, which executes a Go template that includes the querySQL and queryBlocks functions. These functions run arbitrary SELECT statements against the SiYuan SQLite database. An unauthenticated network-adjacent attacker who knows a valid block ID can exfiltrate all user note content, tags, asset references, and block attributes from the database. This vulnerability is fixed in 3.7.0.","published":"2026-06-24T21:15:14.983Z","modified":"2026-08-12T03:51:25.788139232Z","cvss":{"score":5.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":{"score":0.00377,"percentile":0.30849,"asOf":"2026-09-08"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/siyuan-note/siyuan/kernel","fixedVersion":"0.0.0-20260628153353-2d5d72223df4"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54068.json"},{"type":"ADVISORY","url":"https://github.com/siyuan-note/siyuan/security/advisories/GHSA-gcm7-57gf-953c"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54068"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:25.788139232Z"}}
