CVE-2026-20233 is a cross-site scripting (XSS) vulnerability in the web-based user interface of Cisco Webex Meetings. It allows an unauthenticated remote attacker to execute arbitrary script code in a user's browser by persuading the user to follow a malicious link. Cisco has addressed this vulnerability in the Webex Meetings service, and no customer action is needed.

This vulnerability arises from insufficient validation of user input in the Cisco Webex Meetings web interface, enabling an attacker to conduct a cross-site scripting attack. Exploitation requires user interaction, such as clicking a malicious link, which could lead to execution of arbitrary scripts in the victim's browser or access to sensitive browser-based information. Cisco has remediated this issue within the Webex Meetings service itself.
