CVE-2026-76360

Information Disclosure through Missing Authorization in the Health REST API in Splunk SOAR

In Splunk SOAR versions below 8.6.0, an authenticated user with no role assigned could use the /rest/health endpoint to gather system and cluster telemetry that should be restricted to administrative or support users. The vulnerability is a missing authorization check, where the endpoint does not verify that the caller holds a role permitted to view system health and cluster state. 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) and Monitor the health of your Splunk SOAR (On-premises) system (https://help.splunk.com/en/splunk-soar/soar-on-premises/administer-soar-on-premises/8.5.0/manage-your-splunk-soar-on-premises-system-health-and-performance/monitor-the-health-of-your-splunk-soar-on-premises-system) in the Splunk documentation.

CVE-2026-76359

Path Traversal through Universal Forwarder Installer Archive Extraction in Splunk SOAR

In Splunk SOAR versions below 8.6.0, a user who holds the Administrator role could use path traversal in the Universal Forwarder installer's archive extraction to write files outside the intended installation directory. The vulnerability is possible because the Universal Forwarder credentials-package extraction workflow does not verify that each archive member remains within the intended destination before extraction. 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) and Configure forwarders to send SOAR data to your Splunk deployment (https://help.splunk.com/en/splunk-soar/soar-on-premises/administer-soar-on-premises/8.5.0/configure-administration-settings-in-splunk-soar-on-premises/configure-forwarders-to-send-soar-data-to-your-splunk-deployment) in the Splunk documentation.

Path Traversal through App Installation Tar Extraction in Splunk SOAR

In Splunk SOAR versions below 8.6.0, a user with app-install privileges could use path traversal during app installation to write files outside the intended temporary directory. The vulnerability is a path traversal in the archive extraction routine, which does not validate that extracted file paths stay within the intended destination directory.

Remote Code Execution (RCE) through Path Traversal in the REST API in Splunk SOAR

In Splunk SOAR versions below 8.6.0, an authenticated user with no role assigned could submit a crafted file path to the Representational State Transfer (REST) API and execute arbitrary code. The vulnerability is possible because the REST API does not require an assigned role for the request and does not restrict the user-supplied file path to the intended temporary directory.

Information Disclosure through Action Parameters in Splunk Attack Analyzer Connector for Splunk SOAR

In versions below 2.2.1 of the Splunk Attack Analyzer Connector for Splunk SOAR, a user who holds a role with permission to run actions could expose a sensitive archive password by invoking either the detonate file or detonate url action, because the action's archive_password parameter is not masked and is shown in cleartext in the user interface.

In Splunk Enterprise 10.2 versions below 10.2.4 and 10 versions below 10.0.7, an unauthenticated user could create or truncate arbitrary files through a PostgreSQL sidecar service endpoint. The vulnerability exists because the PostgreSQL sidecar service endpoint lacks authentication controls, allowing any network-reachable user to invoke file operations without credentials. Splunk Enterprise versions 9.4 and earlier are not affected. If you cannot immediately upgrade to a fixed version, you can mitigate this vulnerability by disabling the PostgreSQL sidecar service.
