CVSS medium 6.5

Overview

Description
In Splunk SOAR versions below 8.6.0, a user with a valid Splunk SOAR account could use Representational State Transfer (REST) API filtering on playbook runs to recover session tokens that compromise all data available to the affected user. The information disclosure is possible because Splunk SOAR does not block REST API filters from matching values that responses otherwise hide. For more information see REST Run Playbook (https://help.splunk.com/en/splunk-soar/soar-cloud/rest-api-reference/run-playbook-endpoints/rest-run-playbook) in the Splunk documentation.

  1. In Splunk SOAR versions below 8.6.0, a user who holds the OnPrem Broker role could write files outside the intended Automation Broker log directory. The vulnerability is possible because Automation Broker log uploads accept crafted filename input before writing log files. For more information see Manage roles and permissions in Splunk SOAR (Cloud) (https://help.splunk.com/en/splunk-soar/soar-cloud/administer-soar-cloud/manage-your-splunk-soar-cloud-users-and-accounts/manage-roles-and-permissions-in-splunk-soar-cloud) and About Splunk SOAR Automation Broker (https://help.splunk.com/en/splunk-soar/splunk-automation-broker/about-splunk-soar-automation-broker/about-splunk-soar-automation-broker) in the Splunk documentation.•CVE-2026-76369
  2. In Splunk SOAR versions below 8.6.0, a user who holds the "Incident Commander" Splunk SOAR role could store JavaScript in a note and run it in the browser of another user when that user opens the note. The stored Cross-Site Scripting (XSS) vulnerability is possible because Splunk SOAR can treat existing note content as Hypertext Markup Language (HTML) without sanitizing that content when the note format changes. The vulnerability requires the attacker to phish the affected user by tricking them into initiating a request within their browser. The user who holds the "Incident Commander" Splunk SOAR role should not be able to exploit the vulnerability at will. For more information see Manage roles and permissions in Splunk SOAR (Cloud) (https://help.splunk.com/en/splunk-soar/soar-cloud/administer-soar-cloud/manage-your-splunk-soar-cloud-users-and-accounts/manage-roles-and-permissions-in-splunk-soar-cloud) in the Splunk documentation.•CVE-2026-76367
  3. In Splunk SOAR versions below 8.6.0, an authenticated user with restricted tenant access could use the Representational State Transfer (REST) API to view the names and identifiers of tenants that fall outside the role scope for that user. The vulnerability is possible because Splunk SOAR does not enforce role-based tenant restrictions when it returns tenant information through the REST API in deployments with multi-tenancy turned on. For more information see REST Roles and Permissions (https://help.splunk.com/en/splunk-soar/soar-cloud/rest-api-reference/role-management-endpoints/rest-roles-and-permissions) and Configure multiple tenants on your Splunk SOAR (On-premises) instance (https://help.splunk.com/en/splunk-soar/soar-on-premises/administer-soar-on-premises/7.1.0/configure-product-settings-for-your-splunk-soar-on-premises-instance/configure-multiple-tenants-on-your-splunk-soar-on-premises-instance) in the Splunk documentation.•CVE-2026-76370
  4. In Splunk SOAR versions below 8.6.0, a user who holds a role that contains the playbooks:view permission could view metadata about a playbook repository that they are not authorized to view. The vulnerability is possible because Playbook History does not check repository permissions before returning playbook revision metadata. For more information see Manage roles and permissions in Splunk SOAR (Cloud) (https://help.splunk.com/en/splunk-soar/soar-cloud/administer-soar-cloud/manage-your-splunk-soar-cloud-users-and-accounts/manage-roles-and-permissions-in-splunk-soar-cloud) and Manage settings for a playbook in Splunk SOAR (Cloud) (https://help.splunk.com/en/splunk-soar/soar-cloud/build-playbooks/manage-playbooks-and-playbook-settings/manage-settings-for-a-playbook-in-splunk-soar-cloud) in the Splunk documentation.•CVE-2026-76368
  5. In Splunk SOAR versions below 8.6.0, a user with the "Administrator" role could use the /rest/support/connectivity/.../check_connectivity endpoint to make Splunk SOAR initiate outbound network connections to arbitrary destinations and determine whether internal hosts and ports are reachable. The Server-Side Request Forgery (SSRF) is possible because the connectivity check REST API does not sufficiently validate the destination before Splunk SOAR connects to it. For more information see Manage roles and permissions in Splunk SOAR (On-premises) (https://help.splunk.com/en/splunk-soar/soar-on-premises/administer-soar-on-premises/8.5.0/manage-your-splunk-soar-on-premises-users-and-accounts/manage-roles-and-permissions-in-splunk-soar-on-premises) in the Splunk documentation.•CVE-2026-76361
