CVE-2026-20203 Details
Description
In Splunk Enterprise versions below 10.2.2, 10.0.5, 9.4.10, and 9.3.11, and Splunk Cloud Platform versions below 10.4.2603.0, 10.3.2512.6, 10.2.2510.10, 10.1.2507.19, 10.0.2503.13, and 9.3.2411.127, a low-privileged user that does not hold the `admin` or `power` Splunk roles, has write permission on the app, and does not hold the high-privilege capability `accelerate_datamodel`, could turn on or off Data Model Acceleration due to improper access control.
A vulnerability exists in Splunk Enterprise versions prior to 10.2.2, 10.0.5, 9.4.10, and 9.3.11, as well as in Splunk Cloud Platform versions prior to 10.4.2603.0, 10.3.2512.6, 10.2.2510.10, 10.1.2507.19, 10.0.2503.13, and 9.3.2411.127. In these versions, a low-privileged user without 'admin' or 'power' roles, but with write permission on the app and lacking the 'accelerate_datamodel' capability, could improperly enable or disable Data Model Acceleration due to inadequate access controls.
Users of Splunk Enterprise should upgrade to versions 10.2.2, 10.0.5, 9.4.10, or 9.3.11. For Splunk Cloud Platform users, no action is needed as Splunk is actively monitoring and patching instances.
