CVE-2026-76355

Summary

In Splunk Enterprise 10.4 versions below 10.4.2, an unauthenticated user could retrieve the information contained in Edge Processor pipeline configurations through a Representational State Transfer (REST) API endpoint when Edge Processor is turned on. The vulnerability does not affect versions prior to 10.4. The vulnerability exists because the Edge Processor service endpoint lacks authentication controls. For more information see System architecture of the Edge Processor solution (https://help.splunk.com/en/splunk-enterprise/process-data-at-the-edge/use-edge-processors-for-splunk-enterprise/10.4/how-the-edge-processor-solution-works/system-architecture-of-the-edge-processor-solution) in the Splunk documentation.

Affected Software

Weaknesses

• CWE-306: The software does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources.

Workarounds

Turn off Edge Processor by setting edge_processor_enabled = false in the server.conf configuration file if you do not use Edge Processor. For more information see Sidecar configuration settings in the Splunk documentation.
