Kerentanan Improper Restriction of Excessive Authentication Attempts. Skor CVSS 3.1 7.5 (High) menurut vulncheck.com.

Deskripsi (NVD)

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.
