{"apiVersion":"1.0","identifier":"CVE-2026-74868","description":"SiYuan versions before 3.7.4 contain an unthrottled brute-force vulnerability in the Publish Service Basic Auth implementation (PublishServiceTransport.RoundTrip() in kernel/server/proxy/publish.go). 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.","publishedAt":"2026-08-17T11:16:41","lastModifiedAt":"2026-08-26T16:57:52","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74868","cvssScore":7.5,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","epssProbability":0.00375,"riskScore":0.78,"affectedProduct":"SiYuan","affectedVersions":"<3.7.4","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74868","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74868","en":"https://www.redsauce.net/en/cves/CVE-2026-74868","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74868","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74868","de":"https://www.redsauce.net/de/cves/CVE-2026-74868","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74868","el":"https://www.redsauce.net/el/cves/CVE-2026-74868"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74868"}}
