CVE-2026-40412
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedUnrestricted upload of file with dangerous type in Azure Orbital Spatio allows an unauthorized attacker to execute code over a network.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceUnrestricted file upload vulnerability in Azure Orbital Spatio permits an unauthenticated attacker to upload files of dangerous types, potentially leading to remote code execution. The CVSS 9.8 score indicates trivial exploitability with network-based attack vector and complete compromise of the system.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Azure Orbital Spatio usageIn the Azure Portal, search for 'Orbital' under All Resources or check your subscription's resource inventory for any Azure Orbital Spatio resources deployedAffected if Any Azure Orbital Spatio resource exists in the subscription
-
Verify network exposure of the Orbital Spatio endpointExamine the network configuration for the Azure Orbital Spatio resource. Check whether the Spatio endpoint is exposed to the public internet or accessible from untrusted networks by reviewing the VNet configuration, NSG rules, and any firewall settingsAffected if The Orbital Spatio endpoint is reachable from public internet or untrusted networks
-
Confirm authentication configurationReview the Azure Orbital Spatio resource settings in the Azure Portal under 'Configuration' or 'Security' to verify whether anonymous or unauthenticated access is permitted to the file upload functionalityAffected if Anonymous or unauthenticated access is enabled for the file upload feature
-
Inspect recent file upload activityCheck Azure Activity Logs and Azure Orbital Spatio diagnostic logs for any recent file upload operations, particularly files with executable extensions (.exe, .bat, .ps1, .sh, .dll) or suspicious file typesAffected if Unusual or suspicious file uploads are present in the logs
If Azure Orbital Spatio is deployed and its endpoint is network-accessible from untrusted networks, the environment is likely affected by this vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataSince this is a Microsoft Azure service vulnerability, apply available security updates from Microsoft immediately. Implement network segmentation and restrict access to Azure Orbital interfaces while awaiting the vendor patch. Review and monitor file upload operations for anomalous payloads.
