Kerentanan Improper Access Control. Skor CVSS 3.1 4.3 (Medium) menurut github.com.

Deskripsi (NVD)

Warpgate is an open source SSH, HTTPS and MySQL bastion host for Linux. From 0.23.0 until 0.27.3, HTTP API token authentication resolves ConfigProvider::validate_api_token into RequestAuthorization::UserToken without enforcing the owning user's allowed_ip_ranges against the trusted client address in warpgate-protocol-http/src/common.rs. An attacker holding a leaked, phished, or exfiltrated X-Warpgate-Token can therefore use it from a prohibited network location. Deployments without allowed_ip_ranges are unaffected, and HTTP target proxying plus SSH, MySQL, PostgreSQL, RDP, VNC, and Kubernetes paths do not accept this vulnerable HTTP token flow. This issue is fixed in version 0.27.3.
