CVE-2026-76357— Remote Code Execution (RCE) through Path Traversal in the REST API in Splunk SOAR

Quick assessment

Affected
Splunk Splunk SOAR
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Splunk SOAR 8.6.0 之前的版本中，未分配任何角色的已认证用户可通过向代表状态传输（REST）API 提交构造的文件路径来执行任意代码。该漏洞之所以存在，是因为 REST API 在接收请求时不要求用户必须分配特定角色，且未对用户提供的文件路径进行限制，使其不能超出预期的临时目录范围。有关详细信息，请参阅 Splunk 文档中的“在 Splunk SOAR（本地部署版）中管理角色和权限”（https://help.splunk.com/en/splunk-soar/soar-on-premises

Vulnerability Title
Remote Code Execution (RCE) through Path Traversal in the REST API in Splunk SOAR
Source: CVE Program / CVE List V5
Vulnerability Description
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. 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 Splunk SOAR (On-premises) security information (https://help.splunk.com/en/splunk-soar/soar-on-premises/administer-soar-on-premises/8.5.0/introduction-to-splunk-soar-on-premises/splunk-soar-on-premises-security-information) in the Splunk documentation.
