CVE-2026-76372: Incorrect Permission Assignment through Safe Mode in Nmap Scanner for Splunk SOAR
- Severity: medium (CVSS 6.6 v3.1)
- Exploited in the wild: not listed in CISA KEV
- EPSS: 0.4% probability of exploitation in the next 30 days
- Public exploit or detection template: none known
- Published: 2026-08-19 · updated 2026-08-20
- Weakness: CWE-732
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.
