CVE-2025-59545Network attack vector

Stored XSS via raw Prompt command output

Published Sep 23, 2025 · Updated Sep 23, 2025

Stored XSS in DNN Software DNN Platform's Prompt module before 10.1.0 allows remote authenticated users to execute scripts in users' browsers. Prompt commands return attacker-controlled fields as raw HTML, bypassing the sanitization applied when the same input appears in entry forms. Exploitation requires low-privileged access and a user to process the content through an affected command; execution can occur in a super-user's browser context.
