Splunk PDF Export SSRF <10.2.4,10.0.7,9.4.12,9.3.13
CVE-2026-20252 Published on June 10, 2026
Server-Side Request Forgery (SSRF) through Dashboard Studio PDF Export in Splunk Enterprise
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.
Weakness Type
What is a SSRF Vulnerability?
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. By providing URLs to unexpected hosts or ports, attackers can make it appear that the server is sending the request, possibly bypassing access controls such as firewalls that prevent the attackers from accessing the URLs directly. The server can be used as a proxy to conduct port scanning of hosts in internal networks, use other URLs such as that can access documents on the system (using file://), or use other protocols such as gopher:// or tftp://, which may provide greater control over the contents of requests.
CVE-2026-20252 has been classified to as a SSRF vulnerability or weakness.
