CVE-2026-76372— Incorrect Permission Assignment through Safe Mode in Nmap Scanner for Splunk SOAR

Quick assessment

Affected
Splunk Nmap Scanner
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 Nmap Scanner 3.0.15 以下版本中，拥有编辑、创建或运行剧本（playbook）权限的 Splunk SOAR 用户，可以在“安全模式”（Safe Mode）剧本中执行“扫描网络”（scan network）操作，尽管该操作在界面中被列为只读。这可能导致攻击者通过 Nmap 脚本引擎（NSE）脚本，在目标系统上执行命令或进行其他更改。该漏洞产生的原因是：Nmap Scanner 连接器的操作清单（action manifest）将“扫描网络”操作标记为只读，但实际上该操作接受可执行写操作的脚本参

Vulnerability Title
Incorrect Permission Assignment through Safe Mode in Nmap Scanner for Splunk SOAR
Source: CVE Program / CVE List V5
Vulnerability Description
In Nmap Scanner versions below 3.0.15, a user who holds a role that can edit, create, or run playbooks in Splunk SOAR could run the scan network action in a Safe Mode playbook while that action is listed as read-only, which could allow for command execution or other changes on a target system through Nmap Scripting Engine scripts. The vulnerability is possible because the Nmap Scanner connector action manifest classifies the scan network action as read-only even though the action accepts script parameters that can perform write operations. For more information see Manage settings for a playbook in Splunk SOAR (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.
