CVE-2026-76382Network attack vector

Archive password disclosure via unmasked action parameter

Published Aug 19, 2026 · Updated Aug 20, 2026

Cleartext password exposure in Splunk Phantom app for Splunk SOAR before 3.8.5 allows remote authenticated users to read archive passwords. The deflate item action leaves its password parameter unmarked as a password, so Splunk SOAR renders the supplied archive secret unmasked in the action interface. Exploitation requires a role permitted to run actions and exposes only the archive password entered for that action, with no reported integrity or availability impact.
