{"id":"CVE-2026-20117","state":"PUBLISHED","title":"Multiple Cisco Contact Center Products Cross-Site Scripting Vulnerabilities","description":"A vulnerability in the web-based management interface of Cisco Unified Contact Center Express (Unified CCX) could allow an unauthenticated, remote attacker to conduct cross-site scripting (XSS) attacks against a user of the interface.\r\n\r\nThis vulnerability exists because the web-based management interface of an affected system does not sufficiently validate user-supplied input. 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.","publishedAt":"2026-03-11T16:31:26.560Z","updatedAt":"2026-03-11T17:20:21.169Z","severity":{"score":6.1,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","source":"cisco"},"assigner":"cisco","products":["Cisco Cisco Unified Contact Center Express"],"affected":[{"vendor":"Cisco","product":"Cisco Unified Contact Center Express","defaultStatus":"unknown","versions":[{"version":"10.5(1)SU1","status":"affected"},{"version":"10.6(1)","status":"affected"},{"version":"11.6(1)","status":"affected"},{"version":"10.6(1)SU1","status":"affected"},{"version":"10.6(1)SU3","status":"affected"},{"version":"11.6(2)","status":"affected"},{"version":"12.0(1)","status":"affected"},{"version":"11.0(1)SU1","status":"affected"},{"version":"11.5(1)SU1","status":"affected"},{"version":"10.5(1)","status":"affected"},{"version":"12.5(1)","status":"affected"},{"version":"12.5(1)SU1","status":"affected"},{"version":"12.5(1)SU2","status":"affected"},{"version":"12.5(1)SU3","status":"affected"},{"version":"12.5(1)_SU03_ES01","status":"affected"},{"version":"12.5(1)_SU03_ES02","status":"affected"},{"version":"12.5(1)_SU02_ES03","status":"affected"},{"version":"12.5(1)_SU02_ES04","status":"affected"},{"version":"12.5(1)_SU02_ES02","status":"affected"},{"version":"12.5(1)_SU01_ES02","status":"affected"},{"version":"12.5(1)_SU01_ES03","status":"affected"},{"version":"12.5(1)_SU02_ES01","status":"affected"},{"version":"11.6(2)ES07","status":"affected"},{"version":"11.6(2)ES08","status":"affected"},{"version":"12.5(1)_SU01_ES01","status":"affected"},{"version":"12.0(1)ES04","status":"affected"},{"version":"12.5(1)ES02","status":"affected"},{"version":"12.5(1)ES03","status":"affected"},{"version":"11.6(2)ES06","status":"affected"},{"version":"12.5(1)ES01","status":"affected"},{"version":"12.0(1)ES03","status":"affected"},{"version":"12.0(1)ES01","status":"affected"},{"version":"11.6(2)ES05","status":"affected"},{"version":"12.0(1)ES02","status":"affected"},{"version":"11.6(2)ES04","status":"affected"},{"version":"11.6(2)ES03","status":"affected"},{"version":"11.6(2)ES02","status":"affected"},{"version":"11.6(2)ES01","status":"affected"},{"version":"10.6(1)SU3ES03","status":"affected"},{"version":"11.0(1)SU1ES03","status":"affected"},{"version":"10.6(1)SU3ES01","status":"affected"},{"version":"10.5(1)SU1ES10","status":"affected"},{"version":"11.5(1)SU1ES03","status":"affected"},{"version":"11.6(1)ES02","status":"affected"},{"version":"11.5(1)ES01","status":"affected"},{"version":"10.6(1)SU2","status":"affected"},{"version":"10.6(1)SU2ES04","status":"affected"},{"version":"11.6(1)ES01","status":"affected"},{"version":"10.6(1)SU3ES02","status":"affected"},{"version":"11.5(1)SU1ES02","status":"affected"},{"version":"11.5(1)SU1ES01","status":"affected"},{"version":"11.0(1)SU1ES02","status":"affected"},{"version":"12.5(1)_SU03_ES03","status":"affected"},{"version":"12.5(1)_SU03_ES04","status":"affected"},{"version":"12.5(1)_SU03_ES05","status":"affected"},{"version":"UCCX 15.0.1","status":"affected"},{"version":"12.5(1)_SU03_ES06","status":"affected"},{"version":"12.5(1)_SU03_ES07","status":"affected"},{"version":"15.0(1)","status":"affected"},{"version":"15.0(1)ES01","status":"affected"},{"version":"15.0(1)ES-MSOauth","status":"affected"},{"version":"1501_ES01_CSCws06843","status":"affected"}]}],"references":["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-cc-xss-MrNAH5Jh"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:11:10.572Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/20xxx/CVE-2026-20117.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-20117","state":"PUBLISHED","datePublished":"2026-03-11T16:31:26.560Z","dateUpdated":"2026-03-11T17:20:21.169Z","assignerShortName":"cisco","assignerOrgId":"d1c1063e-7a18-46af-9102-31f8928bc633","dateReserved":"2025-10-08T11:59:15.376Z"},"containers":{"cna":{"title":"Multiple Cisco Contact Center Products Cross-Site Scripting Vulnerabilities","descriptions":[{"lang":"en","value":"A vulnerability in the web-based management interface of Cisco Unified Contact Center Express (Unified CCX) could allow an unauthenticated, remote attacker to conduct cross-site scripting (XSS) attacks against a user of the interface.\r\n\r\nThis vulnerability exists because the web-based management interface of an affected system does not sufficiently validate user-supplied input.
