Splunk Mcp Server App
Monthly
Operating-system command execution in the Splunk MCP Server app (all versions below 1.2.1) lets a user already holding the Splunk 'admin' role run arbitrary commands on the underlying host by abusing unsafe deserialization in the credential-management component. Because the app trusts stored data and deserializes it without verifying the object type, a privileged Splunk user can escalate from application-level administration to full host compromise. No public exploit identified at time of analysis, and it is not listed in CISA KEV; a vendor patch is available.
