CRITICAL 9.2

DescriptionCVE.org

Keep (commit 91c75e0) contains a server-side request forgery vulnerability that allows unauthenticated attackers to make the backend issue arbitrary HTTP requests by supplying attacker-controlled host values to the unprotected healthcheck endpoint. Attackers can send a crafted JSON payload with a malicious host parameter to cause the backend to issue outbound requests to internal services or cloud metadata endpoints, enabling theft of cloud credentials and internal network reconnaissance.

AnalysisAI

Server-side request forgery in Keep (keephq/keep) as of commit 91c75e0 lets unauthenticated attackers coerce the backend into issuing arbitrary outbound HTTP requests by POSTing a crafted host value to an unprotected providers healthcheck endpoint. Because the endpoint requires no authentication, a remote attacker can pivot into internal services and cloud metadata endpoints (e.g. 169.254.169.254) to steal cloud credentials and map internal networks. No public exploit identified at time of analysis, though the flaw was reported by VulnCheck and a corresponding GitHub issue is public; the CVSS 4.0 base score is 9.2 (Critical).
