{"id":"CVE-2026-20109","state":"PUBLISHED","title":"Cisco Packaged Contact Center Enterprise and Cisco Unified Contact Center Enterprise Cross-Site Scripting Vulnerability","description":"Multiple vulnerabilities in the web-based management interface of Cisco Packaged Contact Center Enterprise (Packaged CCE) and Cisco Unified Contact Center Enterprise (Unified CCE) could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device. \r\n\r\nThese vulnerabilities exist because the web-based management interface does not properly validate user-supplied input. An attacker could exploit these vulnerabilities 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 these vulnerabilities, the attacker must have valid administrative credentials.","publishedAt":"2026-01-21T16:26:19.268Z","updatedAt":"2026-01-21T16:46:11.154Z","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 Packaged Contact Center Enterprise","Cisco Cisco Unified Contact Center Enterprise"],"affected":[{"vendor":"Cisco","product":"Cisco Packaged Contact Center Enterprise","defaultStatus":"unknown","versions":[{"version":"12.5(1)","status":"affected"},{"version":"11.0(1)","status":"affected"},{"version":"12.0(1)","status":"affected"},{"version":"11.0(2)","status":"affected"},{"version":"11.5(1)","status":"affected"},{"version":"10.5(1)","status":"affected"},{"version":"10.5(2)","status":"affected"},{"version":"11.6(2)","status":"affected"},{"version":"10.5(1)_ES7","status":"affected"},{"version":"11.6(1)","status":"affected"},{"version":"10.5(2)_ES8","status":"affected"},{"version":"12.6(1)","status":"affected"},{"version":"12.5(2)","status":"affected"},{"version":"12.6(2)","status":"affected"},{"version":"15.0(1)","status":"affected"}]},{"vendor":"Cisco","product":"Cisco Unified Contact Center Enterprise","defaultStatus":"unknown","versions":[{"version":"12.6(1)ES3","status":"affected"},{"version":"12.6(1)ES1","status":"affected"},{"version":"12.6(1)","status":"affected"},{"version":"12.6(1)ES2","status":"affected"},{"version":"12.6(1)SecurityPatch","status":"affected"},{"version":"12.5(1)ES1","status":"affected"},{"version":"12.5(1)","status":"affected"},{"version":"12.6(1)ES4","status":"affected"},{"version":"11.0(1)","status":"affected"},{"version":"10.5(1)","status":"affected"},{"version":"12.0(1)","status":"affected"},{"version":"10.5","status":"affected"},{"version":"11.0","status":"affected"},{"version":"11.5","status":"affected"},{"version":"12.6(2)","status":"affected"},{"version":"12.6(2)ES1","status":"affected"},{"version":"12.6(2)ES2","status":"affected"},{"version":"15.0(1)","status":"affected"},{"version":"12.6(2)ES3","status":"affected"},{"version":"15.0(1)ET01","status":"affected"},{"version":"15.0(1)_SP1","status":"affected"},{"version":"15.0(1)ES202508","status":"affected"},{"version":"12.6(2)_ES","status":"affected"}]}],"references":["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ucce-pcce-xss-2JVyg3uD"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:11:10.572Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/20xxx/CVE-2026-20109.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-20109","state":"PUBLISHED","datePublished":"2026-01-21T16:26:19.268Z","dateUpdated":"2026-01-21T16:46:11.154Z","assignerShortName":"cisco","assignerOrgId":"d1c1063e-7a18-46af-9102-31f8928bc633","dateReserved":"2025-10-08T11:59:15.374Z"},"containers":{"cna":{"title":"Cisco Packaged Contact Center Enterprise and Cisco Unified Contact Center Enterprise Cross-Site Scripting Vulnerability","descriptions":[{"lang":"en","value":"Multiple vulnerabilities in the web-based management interface of Cisco Packaged Contact Center Enterprise (Packaged CCE) and Cisco Unified Contact Center Enterprise (Unified CCE) could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device. \r\n\r\nThese vulnerabilities exist because the web-based management interface does not properly validate user-supplied input.
