NVD 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.

    Observability tools need broad network access by design. That's why SSRF in monitoring stacks is so brutal: the blast radius is your entire internal network. Treat these CVEs like RCE. https://nvd.nist.gov/vuln/detail/CVE-2026-63731

    Post summary

    The message highlights that SSRF in observability tools can have a wide internal impact and advises treating related CVEs with the severity of RCE, but it does not provide detailed technical information, PoC, exploit, or patch details.
