Medium severity, CVSS 5.4. EPSS: 0.2% chance of exploitation in the next 30 days.

Cisco has addressed this vulnerability in the Cisco Webex Meetings service, and no customer action is needed. This vulnerability existed because of insufficient validation of user-supplied input to the user profile component of Cisco Webex Meetings.
