{"id":"CVE-2026-20252","state":"PUBLISHED","title":"Server-Side Request Forgery (SSRF) through Dashboard Studio PDF Export in Splunk Enterprise","description":"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.  \n\nThe 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.","publishedAt":"2026-06-10T17:16:19.518Z","updatedAt":"2026-06-10T18:23:36.803Z","severity":{"score":7.6,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:L","source":"cisco"},"assigner":"cisco","products":["Splunk
