Description
In Splunk SOAR versions below 8.7.0, an authenticated user who does not hold a role with permission to edit Automation Brokers could download the Splunk SOAR Automation Broker Docker Compose configuration file. The file contains the Uniform Resource Locator (URL) of the Splunk SOAR instance, the container image location, and the Splunk SOAR Automation Broker version.
The vulnerability is possible because Splunk SOAR returns the configuration file without enforcing the Automation Broker edit permission.

Impact

CVE‑2026‑76304 permits an authenticated Splunk SOAR user who lacks Automation Broker edit permissions to download the broker's Docker Compose configuration file. The file exposes the Splunk SOAR instance URL, the container image location, and the broker version, revealing internal network topology and tooling details. This unauthorized disclosure aligns with CWE‑862 and, while it does not expose passwords or credentials, it provides valuable information to an attacker that could facilitate further reconnaissance or targeted attacks.

Affected Systems

The vulnerable component is Splunk SOAR. The impact applies to all Splunk SOAR releases earlier than version 8.7.0, as the vendor’s mitigation specifically targets upgrades to 8.7.0 or newer. No finer version granularity was supplied in the advisory.

Risk and Exploitability

The CVSS score of 4.3 indicates moderate severity. The EPSS score is unavailable and the vulnerability is not listed in CISA’s KEV catalogue, so there is no evidence of widespread exploitation yet. Nevertheless, any authenticated user who does not have the required edit role can freely retrieve the file, making the attack path trivial for users with basic access privileges inside the organization. No public exploits are documented as of the advisory release.

Remediation

Vendor Solution

Upgrade Splunk SOAR to version 8.7.0 or higher.


OpenCVE Recommended Actions

  • Upgrade Splunk SOAR to version 8.7.0 or later.
  • Verify that only users assigned the Automation Broker edit role can access the configuration download endpoint and enforce permissions consistently.
  • Restrict or remove any publicly exposed endpoints that serve configuration files to prevent accidental disclosure.
