Vulnerability in Nmap Scanner (CVE-2026-76372)
Summary
Vulnerability in Nmap Scanner (CVE-2026-76372). Risk of unauthorized operations or information disclosure.
Original description
The description as published by the source.
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.
