Detailsinfo

A vulnerability was found in Splunk Enterprise and Cloud Platform (the affected version is unknown) and classified as critical. Affected by this issue is an unknown code of the component Dashboard Studio PDF Export. The manipulation with an unknown input leads to a server-side request forgery vulnerability. Using CWE to declare the problem leads to CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. Impacted is confidentiality, integrity, and availability. CVE summarizes:

In Splunk Enterprise versions below 10.2.4, 10.0.7, 9.4.12, and 9.3.13, and Splunk Cloud Platform versions below 10.4.2604.3, 10.3.2512.12, 10.2.2510.14, 10.1.2507.22, and 9.3.2411.132, a low-privileged user that does not hold the "admin" or "power" Splunk roles could send server-side requests to arbitrary internal destinations through the Dashboard Studio PDF export feature. The vulnerability exists because the trusted-domain validation uses a prefix match that can be bypassed with attacker-controlled subdomains (for example, docs.splunk.com.evil.com), and because the PDF export service follows HTTP redirects automatically without re-validating each redirect target against the allowlist.

The advisory is shared for download at advisory.splunk.com. This vulnerability is handled as CVE-2026-20252 since 10/08/2025. The exploitation is known to be easy. The attack may be launched remotely. There are neither technical details nor an exploit publicly available.
