{"id":"CVE-2025-20382","state":"PUBLISHED","title":"URL validation bypass through Views Dashboard in Splunk Enterprise","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.","publishedAt":"2025-12-03T17:00:21.824Z","updatedAt":"2025-12-03T21:28:38.682Z","severity":{"score":3.5,"label":"Low","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:N/A:N","source":"cisco"},"assigner":"cisco","products":["Splunk Splunk Enterprise","Splunk Splunk Cloud Platform"],"affected":[{"vendor":"Splunk","product":"Splunk Enterprise","versions":[{"version":"10.0","status":"affected","lessThan":"10.0.2","versionType":"custom"},{"version":"9.4","status":"affected","lessThan":"9.4.6","versionType":"custom"},{"version":"9.3","status":"affected","lessThan":"9.3.8","versionType":"custom"},{"version":"9.2","status":"affected","lessThan":"9.2.10","versionType":"custom"}]},{"vendor":"Splunk","product":"Splunk Cloud Platform","versions":[{"version":"10.1.2507","status":"affected","lessThan":"10.1.2507.10","versionType":"custom"},{"version":"10.0.2503","status":"affected","lessThan":"10.0.2503.8","versionType":"custom"},{"version":"9.3.2411","status":"affected","lessThan":"9.3.2411.120","versionType":"custom"}]}],"references":["https://advisory.splunk.com/advisories/SVD-2025-1201"],"weaknesses":["CWE-601"],"ingestedAt":"2026-10-29T20:08:39.238Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/20xxx/CVE-2025-20382.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-20382","state":"PUBLISHED","datePublished":"2025-12-03T17:00:21.824Z","dateUpdated":"2025-12-03T21:28:38.682Z","assignerShortName":"cisco","assignerOrgId":"d1c1063e-7a18-46af-9102-31f8928bc633","dateReserved":"2024-10-10T19:15:13.264Z"},"containers":{"cna":{"title":"URL validation bypass through Views Dashboard in Splunk Enterprise","descriptions":[{"lang":"en","value":"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.
