Risk evaluation

A path traversal flaw in the SmartEMS upload handling allows authenticated users to direct upload data outside of the intended directory via the 'Upload-Key' header. In deployments where writable, code-interpreted paths are reachable, this may lead to remote code execution.

Mitigation summary

Restrict access to the SmartEMS Web UI to trusted admin networks/VPN. Enforce strong credentials and rotate or revoke active tokens/sessions.
