{"id":"CVE-2026-76335","state":"PUBLISHED","title":"Remote Code Execution (RCE) through Splunk Web Manager Configuration in Splunk Enterprise","description":"In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, an authenticated user who does not hold a role with the edit_manager_xml capability could write a malicious Splunk Web Manager Extensible Markup Language (XML) configuration. When the same user opens the affected Splunk Web Manager page, Splunk Enterprise runs attacker-controlled operating-system commands as the user account running Splunk Enterprise. The vulnerability is possible because Splunk Web does not require the edit_manager_xml capability before accepting Splunk Web Manager XML configuration changes.","publishedAt":"2026-08-19T21:34:35.810Z","updatedAt":"2026-08-27T16:24:58.589Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","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-94"],"ingestedAt":"2026-10-29T20:12:58.252Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/76xxx/CVE-2026-76335.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-76335","state":"PUBLISHED","datePublished":"2026-08-19T21:34:35.810Z","dateUpdated":"2026-08-27T16:24:58.589Z","assignerShortName":"cisco","assignerOrgId":"d1c1063e-7a18-46af-9102-31f8928bc633","dateReserved":"2026-08-19T12:02:03.627Z"},"containers":{"cna":{"title":"Remote Code Execution (RCE) through Splunk Web Manager Configuration 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, an authenticated user who does not hold a role with the edit_manager_xml capability could write a malicious Splunk Web Manager Extensible Markup Language (XML) configuration.
