CVE-2026-76296: Missing Authorization through Sourcetype Renaming in Splunk Web for Splunk Enterprise
Description
In Splunk Enterprise versions below 10.4.4, 10.2.8, 10.0.11, and 9.4.16, a user who does not hold the "admin" or "power" Splunk roles could create, move, edit, or delete sourcetype renaming configurations that they own in apps that they do not have permission to access. The vulnerability is possible when Splunk Web is turned on because Splunk Web does not verify the required app permissions before it performs sourcetype renaming operations. For more information see Rename source types at search time (https://help.splunk.com/en/splunk-enterprise/get-started/get-data-in/10.6/configure-source-types/rename-source-types-at-search-time) in the Splunk documentation.
