CVE-2026-76251: The software does not perform an authorization check when an actor attempts to access a resource or perform an action. in Splunk Splunk Enterprise
In Splunk Enterprise versions below 10.4.2, 10.2.6, and 10.0.9, a user who does not hold the "admin" or "power" Splunk roles could cause the Splunk App for Splunk Observability Cloud to forward requests to Splunk Observability Cloud, including the Splunk Observability Cloud access token stored for the app. With this access, the user could view all relevant data available to that token and make limited changes to Splunk Observability Cloud content. The vulnerability does not affect Splunk Enterprise 9.4 and 9.3 versions. The vulnerability is possible because the app's Representational State Transfer (REST) API endpoint handlers do not enforce the read_o11y_content capability before forwarding requests with the stored access token. For more information see Define roles on the Splunk platform with capabilities (https://help.splunk.com/en/splunk-enterprise/administer/manage-users-and-security/10.2/manage-splunk-platform-users-and-roles/define-roles-on-the-splunk-platform-with-capabilities) in the Splunk documentation.
