Description
A vulnerability in Cisco Webex Teams, formerly Cisco Spark, could allow an authenticated, remote attacker to view and modify data for an organization other than their own organization.

An attacker who has administrator or compliance officer privileges for one organization account could exploit this vulnerability by using those privileges to view and modify data for another organization account. No customer data was impacted by this vulnerability.
