CVE-2026-20117 — Multiple Cisco Contact Center Products Cross-Site Scripting Vulnerabilities

Description (CNA)

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. This 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.
