CVE-2026-76305 in SOAR
Summary
by MITRE • 10/22/2026
In Splunk SOAR versions below 8.7.0, an authenticated user who does not hold a role with permission to view apps could download an archive of an installed app. This could expose all data in the app archive, including proprietary source code and sensitive information. The vulnerability is possible because Splunk SOAR does not verify permission to view apps before it returns the app archive. For more information see Export or import an app (https://help.splunk.com/en/splunk-soar/soar-on-premises/develop-apps/8.4.0/develop-an-app-using-the-splunk-soar-app-wizard/export-or-import-an-app) and 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.

Analysis

A critical authorization bypass vulnerability exists within Splunk SOAR versions prior to 8.7.0, specifically affecting authenticated users who lack explicit permissions to view applications. This flaw allows such unauthorized individuals to download complete archives of installed apps through a specific endpoint that fails to enforce proper access control checks before generating and returning the archive file. The core technical deficiency lies in the application logic which does not verify whether the requesting user holds the necessary role or permission set required to inspect app metadata or contents prior to executing the export operation. Consequently, any authenticated account can bypass standard security boundaries designed to restrict visibility of proprietary assets within the platform.
The operational impact of this vulnerability is severe due to the nature of Splunk SOAR applications which often contain sensitive intellectual property and confidential data. The downloaded archive includes all components of the app such as proprietary source code configuration files, API keys, credentials embedded in playbooks or integrations, and potentially customer-specific logic that defines automated response workflows. Exposure of this information compromises not only the confidentiality of the software vendor but also the security posture of organizations relying on these apps for their Security Orchestration Automation and Response operations. Attackers with access to such archives can reverse engineer proprietary algorithms extract sensitive credentials for lateral movement or further exploitation within the network, leading to potential data breaches and loss of competitive advantage.
This vulnerability aligns closely with CWE-284 Improper Access Control as it represents a failure in the application to enforce appropriate restrictions on authenticated users regarding specific resources. From an offensive security perspective this behavior is consistent with ATT&CK technique T1530 Data from Cloud Object Storage or more broadly data exfiltration via unauthorized access mechanisms where sensitive files are retrieved without proper authorization checks. The lack of server-side validation for app viewing permissions creates a direct path for information disclosure that undermines the principle of least privilege fundamental to secure system design.
To mitigate this risk organizations running Splunk SOAR on-premises must immediately upgrade to version 8.7.0 or later where the vendor has implemented proper authorization checks before allowing app archive downloads. Until an upgrade is feasible administrators should restrict access to the affected endpoints by configuring network-level controls such as firewalls or reverse proxies that limit who can interact with those specific API routes based on IP address or other trusted criteria rather than relying solely on application-level permissions which are currently flawed. Additionally reviewing and tightening role-based access control policies ensures that only essential personnel have elevated privileges reducing the attack surface for potential exploitation by compromised accounts or insider threats. Regular auditing of user roles and permission assignments further strengthens defense in depth against such authorization bypasses ensuring compliance with industry best practices for secure software development and deployment.
