CVE-2026-63731 Details
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.
A server-side request forgery (SSRF) vulnerability has been identified in HyperDX versions prior to 2.31.0. This vulnerability 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. The vulnerability arises from a lack of URL validation or allowlist enforcement, enabling access to internal APIs, container services, and cloud provider metadata endpoints. Exploitation of this vulnerability can be combined with the reflected error responses from the endpoint, which disclose internal service response bodies.
Users can update to HyperDX version 2.31.0 or later, where this vulnerability has been addressed.
