{"id":"CVE-2026-20047","state":"PUBLISHED","title":"Cisco Identity Services Engine Cross-Site Scripting Vulnerability","description":"A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC) could allow an authenticated, remote attacker to conduct cross-site scripting (XSS) attacks against a user of the interface.\r\n\r\nThis vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected system. An attacker could exploit this vulnerability by injecting malicious code into specific pages of the interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information. To exploit this vulnerability, the attacker must have valid administrative credentials.","publishedAt":"2026-01-15T16:32:15.578Z","updatedAt":"2026-02-26T15:04:06.757Z","severity":{"score":4.8,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N","source":"cisco"},"assigner":"cisco","products":["Cisco Cisco Identity Services Engine Software"],"affected":[{"vendor":"Cisco","product":"Cisco Identity Services Engine Software","defaultStatus":"unknown","versions":[{"version":"3.1.0","status":"affected"},{"version":"3.1.0 p1","status":"affected"},{"version":"3.1.0 p3","status":"affected"},{"version":"3.1.0 p2","status":"affected"},{"version":"3.2.0","status":"affected"},{"version":"3.1.0 p4","status":"affected"},{"version":"3.1.0 p5","status":"affected"},{"version":"3.2.0 p1","status":"affected"},{"version":"3.1.0 p6","status":"affected"},{"version":"3.2.0 p2","status":"affected"},{"version":"3.1.0 p7","status":"affected"},{"version":"3.3.0","status":"affected"},{"version":"3.2.0 p3","status":"affected"},{"version":"3.2.0 p4","status":"affected"},{"version":"3.1.0 p8","status":"affected"},{"version":"3.2.0 p5","status":"affected"},{"version":"3.2.0 p6","status":"affected"},{"version":"3.1.0 p9","status":"affected"},{"version":"3.3 Patch 2","status":"affected"},{"version":"3.3 Patch 1","status":"affected"},{"version":"3.3 Patch 3","status":"affected"},{"version":"3.4.0","status":"affected"},{"version":"3.2.0 p7","status":"affected"},{"version":"3.3 Patch 4","status":"affected"},{"version":"3.4 Patch 1","status":"affected"},{"version":"3.1.0 p10","status":"affected"},{"version":"3.3 Patch 5","status":"affected"},{"version":"3.3 Patch 6","status":"affected"},{"version":"3.4 Patch 2","status":"affected"},{"version":"3.3 Patch 7","status":"affected"},{"version":"3.4 Patch 3","status":"affected"}]}],"references":["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ise-xss-964cdxW5"],"weaknesses":["CWE-80"],"ingestedAt":"2026-10-29T20:11:10.572Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/20xxx/CVE-2026-20047.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-20047","state":"PUBLISHED","datePublished":"2026-01-15T16:32:15.578Z","dateUpdated":"2026-02-26T15:04:06.757Z","assignerShortName":"cisco","assignerOrgId":"d1c1063e-7a18-46af-9102-31f8928bc633","dateReserved":"2025-10-08T11:59:15.355Z"},"containers":{"cna":{"title":"Cisco Identity Services Engine Cross-Site Scripting Vulnerability","descriptions":[{"lang":"en","value":"A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) and Cisco ISE Passive Identity Connector (ISE-PIC) could allow an authenticated, remote attacker to conduct cross-site scripting (XSS) attacks against a user of the interface.\r\n\r\nThis vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected system.
