CVE-2026-49120 Details
Description
Medplum before 5.1.14 contains a server-side request forgery vulnerability in the subscription worker that allows authenticated users to perform unauthorized internal network requests by creating FHIR Subscription resources with arbitrary endpoint URLs. Attackers can point subscription endpoints at internal addresses such as cloud instance metadata services, internal databases, or container orchestration endpoints to exfiltrate IAM credentials and patient health records via the POST body containing full FHIR resource payloads.
A server-side request forgery (SSRF) vulnerability has been identified in Medplum versions prior to 5.1.14. This vulnerability allows authenticated users to make unauthorized internal network requests through the subscription worker. By creating FHIR Subscription resources with arbitrary endpoint URLs, attackers can direct these requests to internal services such as cloud metadata endpoints, internal databases, or container orchestration services. This could lead to the exfiltration of IAM credentials and patient health records, as the POST body would contain full FHIR resource payloads.
Users can update to Medplum version 5.1.14 or later, where this vulnerability has been patched.
