{"id":"CVE-2026-20059","state":"PUBLISHED","title":"Cisco Unity Connection Reflected Cross-Site Scripting Vulnerability","description":"A vulnerability in the web-based management interface of Cisco Unity Connection could allow an unauthenticated, remote attacker to conduct a reflected XSS attack against a user of the interface.\r\n\r\nThis vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by persuading a user to click a crafted link. 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":"2026-04-15T16:11:22.828Z","updatedAt":"2026-04-15T16:56:33.949Z","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 Unity Connection"],"affected":[{"vendor":"Cisco","product":"Cisco Unity Connection","defaultStatus":"unknown","versions":[{"version":"14","status":"affected"},{"version":"14SU1","status":"affected"},{"version":"14SU2","status":"affected"},{"version":"14SU3","status":"affected"},{"version":"14SU3a","status":"affected"},{"version":"15","status":"affected"},{"version":"15SU1","status":"affected"},{"version":"14SU4","status":"affected"},{"version":"15SU2","status":"affected"},{"version":"15SU3","status":"affected"},{"version":"14SU5","status":"affected"},{"version":"15SU4","status":"affected"}]}],"references":["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-unity-vulns-n2EJSbbw"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:11:10.572Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/20xxx/CVE-2026-20059.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-20059","state":"PUBLISHED","datePublished":"2026-04-15T16:11:22.828Z","dateUpdated":"2026-04-15T16:56:33.949Z","assignerShortName":"cisco","assignerOrgId":"d1c1063e-7a18-46af-9102-31f8928bc633","dateReserved":"2025-10-08T11:59:15.356Z"},"containers":{"cna":{"title":"Cisco Unity Connection Reflected Cross-Site Scripting Vulnerability","descriptions":[{"lang":"en","value":"A vulnerability in the web-based management interface of Cisco Unity Connection could allow an unauthenticated, remote attacker to conduct a reflected XSS attack against a user of the interface.\r\n\r\nThis vulnerability exists because the web-based management interface does not properly validate user-supplied input.
