CVE-2026-76293Remote Code Execution (RCE) through Splunk Web Manager Extensible Markup Language (XML) in Splunk Enterprise
High 7.2
In plain English
A high-severity code injection in Splunk Enterprise from Splunk. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.5% (higher than 41% of all known vulnerabilities).
Official description
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.
