What is CVE-2026-20109?

Multiple vulnerabilities exist within the web-based management interface of Cisco Packaged Contact Center Enterprise and Cisco Unified Contact Center Enterprise. These vulnerabilities stem from insufficient validation of user-supplied input, enabling an authenticated remote attacker to conduct cross-site scripting (XSS) attacks on users. By injecting malicious scripts into specific pages of the interface, an attacker could execute arbitrary code in the context of the affected interface, potentially accessing sensitive information stored in the user's browser. Exploitation requires valid administrative credentials.
