The Publish Service runs on a separate, unauthenticated-by-default listener (default TCP port 6808) and gates named publish-viewer accounts (Conf.Publish.Auth.Accounts) with Basic Auth that has no rate limiting, per-account lockout, or backoff. Unauthenticated remote attackers can submit unlimited password guesses against named accounts to gain access to published notes/notebooks.","published":"2026-08-17T11:16:41.030","modified":"2026-08-17T11:16:41.030","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/siyuan-note/siyuan/security/advisories/GHSA-phg7-xcr4-q5wg"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/siyuan-before-brute-force-authentication-via-publish-service"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-17T11:16:41.030"}}
