Remote Code Execution (RCE) through Splunk Web Manager Extensible Markup Language (XML) in Splunk Enterprise

Splunk Enterprise · CVE-2026-76293
0 news outlets0 CERTs and agencies0 researchers

What is it?

In Splunk Enterprise versions below 10.4.3, 10.2.8, 10.0.11, and 9.4.16, a user that holds a role with the edit_manager_xml capability could execute arbitrary operating-system commands using the permissions of the user account running Splunk Enterprise by opening the affected configuration in the Splunk Web Manager page. The vulnerability is possible because Splunk Web evaluates user-controlled expressions from Manager XML without sufficiently restricting the expression syntax.
