This is because the 'edit_user' capability does not honor the 'grantableRoles' setting in the authorize.conf configuration file, which prevents this scenario from happening. Solution For Splunk Enterprise, upgrade versions to 9.0.5, 8.2.11, 8.1.14, or higher. For Splunk Cloud Platform, Splunk is actively patching and monitoring the Splunk Cloud instances. Product Status Product Version Component Affected Version Fix Version Splunk Enterprise 8.1 Splunk Web 8.1.0 to 8.1.13 8.1.14 Splunk Enterprise 8.2 Splunk Web 8.2.0 to 8.2.10 8.2.11 Splunk Enterprise 9.0 Splunk Web 9.0.0 to 9.0.4 9.0.5 Splunk Cloud Platform Splunk Web 9.0.2303 and below 9.0.2303.100 Mitigations and Workarounds Confirm that no role, other than the admin role or its equivalent, has the 'edit_user' capability assigned to it. Confirm that you neither assign the 'edit_user' capability to a role from which other roles inherit, nor that you assign a role with the capability to a user with low or no privileges.
