{"id":"CVE-2026-76325","state":"PUBLISHED","title":"Stored Cross-Site Scripting (XSS) through Splunk Web in Splunk Enterprise","description":"In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user who holds the \"power\" Splunk role could store a malicious ui-tour knowledge object that matches an auto-tour page name and share the object at the app level. The object can execute arbitrary JavaScript in the browser of another authenticated user who visits a standard Splunk Web page. The JavaScript could expose all relevant data and affect system integrity within the second user permissions. The Cross-Site Scripting (XSS) vulnerability is possible because Splunk Web resolves auto-tour entries from the app namespace and uses untrusted tour content when building the tour image.","publishedAt":"2026-08-19T21:34:29.789Z","updatedAt":"2026-08-26T15:22:35.153Z","severity":{"score":7.3,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:N","source":"cisco"},"assigner":"cisco","products":["Splunk Splunk Enterprise"],"affected":[{"vendor":"Splunk","product":"Splunk Enterprise","versions":[{"version":"10.4","status":"affected","lessThan":"10.4.2","versionType":"custom"},{"version":"10.2","status":"affected","lessThan":"10.2.6","versionType":"custom"},{"version":"10.0","status":"affected","lessThan":"10.0.9","versionType":"custom"},{"version":"9.4","status":"affected","lessThan":"9.4.14","versionType":"custom"}]}],"references":["https://advisory.splunk.com/advisories/SVD-2026-0801"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:12:58.252Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/76xxx/CVE-2026-76325.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-76325","state":"PUBLISHED","datePublished":"2026-08-19T21:34:29.789Z","dateUpdated":"2026-08-26T15:22:35.153Z","assignerShortName":"cisco","assignerOrgId":"d1c1063e-7a18-46af-9102-31f8928bc633","dateReserved":"2026-08-19T12:02:03.626Z"},"containers":{"cna":{"title":"Stored Cross-Site Scripting (XSS) through Splunk Web in Splunk Enterprise","descriptions":[{"lang":"en","value":"In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user who holds the \"power\" Splunk role could store a malicious ui-tour knowledge object that matches an auto-tour page name and share the object at the app level.
