Last updated on: 2026-08-31

Assigner: VulDB

Description
A flaw has been found in NASA earthdata-search 1.0.0. Affected by this issue is the function OpenSearchGranuleSearchLambda of the file serverless/src/openSearchGranuleSearch/handler.js of the component granules Endpoint. Executing a manipulation of the argument openSearchOsdd can lead to server-side request forgery. The attack can be launched remotely. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Executive Summary

CVE-2026-82802 is an unauthenticated Server-Side Request Forgery (SSRF) vulnerability in NASA Earthdata Search affecting version 1.0.0 and earlier. The flaw exists in the OpenSearch granule endpoint where the POST /opensearch/granules endpoint accepts an attacker-controlled openSearchOsdd URL. The server fetches this URL, extracts a template URL from the OpenSearch Description Document, and then fetches that template URL without validating the scheme, host, or IP. Both requests are attacker-controlled, allowing unauthenticated access to internal resources.

Detection Guidance

To detect this SSRF vulnerability in NASA Earthdata Search 1.0.0 or earlier, monitor network traffic for outbound requests from the server to internal or external URLs triggered by POST requests to /opensearch/granules with an openSearchOsdd parameter. Check logs for unexpected server-side fetches of arbitrary URLs.

Impact Analysis

This vulnerability allows unauthenticated attackers to access internal resources by manipulating the openSearchOsdd parameter. The endpoint reflects the raw response body of the second request, enabling full read access to internal services returning text, HTML, or XML. Attackers can exfiltrate responses, access cloud metadata, and pivot via redirects to other internal systems.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, potentially violating GDPR (data protection) and HIPAA (health information privacy) by exposing internal resources or exfiltrating confidential information. Compliance may be impacted if internal systems handle regulated data.

Mitigation Strategies

Immediately upgrade NASA Earthdata Search to a patched version if available. If no patch exists, disable the /opensearch/granules endpoint or restrict access to trusted users. Implement strict input validation for the openSearchOsdd parameter and block requests to internal IP ranges or sensitive URLs.
