Victim redirection via custom dashboard background
Published Dec 3, 2025 · Updated Dec 3, 2025
Open redirect in Splunk Enterprise and Splunk Cloud Platform allows remote authenticated users to redirect victims to malicious sites. A low-privileged user can set a Views dashboard custom background to a crafted data:image/png;base64 URL that bypasses the external URL warning. The attacker cannot trigger the redirect at will; a victim must initiate the browser request, after which the browser is sent to an external malicious site.
