CVE-2026-76371Network attack vector

Unauthorized file-list writes via misclassified read-only action

Published Aug 19, 2026 · Updated Aug 20, 2026

Improper authorization in Splunk FireAMP before 2.1.15 allows remote authenticated users to modify file lists via Safe Mode playbooks. The FireAMP connector manifest marks the add listitem action as read-only even though that action writes to file lists, so Splunk SOAR Safe Mode permits an update operation that should be blocked. Exposure requires a role that can edit, create, or run playbooks, and the documented consequence is unauthorized file-list modification rather than broader code execution or data disclosure.
