Published Mar 26, 2025 · Updated Mar 27, 2025

Improper input validation in affected Splunk Dashboard Studio releases allows remote authenticated users to disclose information through external content. The vendor identifies a bypass of the external-content warning modal but has not published the input, code locus, or validation error that permits it. The issue requires a low-privileged account without the admin or power role, affects listed Enterprise and Cloud Platform releases when Splunk Web is enabled, and has confidentiality impact only.
