Vulnerability Title
HyperDX < 2.31.0 SSRF via ClickHouse Proxy Test Endpoint
Source: CVE Program / CVE List V5
Vulnerability Description
HyperDX before 2.31.0 contains a server-side request forgery vulnerability that allows authenticated team members to direct the server to arbitrary internal destinations by supplying a caller-controlled host parameter to the ClickHouse proxy test endpoint with no URL validation or allowlist enforcement. Attackers can exploit the reflected error responses from the endpoint to disclose internal service response bodies, enabling access to internal APIs, container services, and cloud provider metadata endpoints.
