CVE-2025-20367 is a cross-site scripting vulnerability in Splunk Enterprise and Splunk Cloud Platform. In affected versions of Splunk Enterprise prior to 9.4.4, 9.3.6, and 9.2.8, and affected Splunk Cloud Platform versions prior to 9.3.2411.109, 9.3.2408.119, and 9.2.2406.122, a low-privileged authenticated user who does not hold the admin or power role can craft a malicious payload via the dataset.command parameter of the /app/search/table endpoint. If the payload is processed and rendered in another user's browser, it can trigger unauthorized JavaScript execution in that browser context. The issue is an improper neutralization of untrusted input in a web application workflow, enabling stored or reflected script execution depending on how the crafted request is delivered and viewed.
