CVE-2026-121421

MediumCVSS 4.3/10Last modified Nov 3, 2026

Description

SurrealDB 3.1.0 before 3.3.0 contains a server-side request forgery vulnerability in network-capability matching because port-specific --deny-net rules (HOST:PORT or IP:PORT) match only a literal host string, while the resolved-IP check discards the port. Authenticated users can call http::* functions with a hostname resolving to a denied IP, or the IP of a denied hostname, to reach blocked internal services.
