CVE-2019-19362: An issue was discovered in the Chat functionality of the TeamViewer desktop application 14.3.4730 on Windows.

An issue was discovered in the Chat functionality of the TeamViewer desktop application 14.3.4730 on Windows. (The vendor states that it was later fixed.) Upon login, every communication is saved within Windows main memory. When a user logs out or deletes conversation history (but does not exit the application), this data is not wiped from main memory, and therefore could be read by a local user with the same or greater privileges.

Security readout for executives and security teams

This CVE describes TeamViewer for Windows leaving chat communications in memory after logout or conversation deletion, as long as the application stays running. A local user with equal or higher privileges could potentially recover sensitive chat content. The vendor reportedly fixed it later, but the provided sources do not name a fixed version. Exposure is limited to Windows endpoints running TeamViewer desktop 14.3.4730 where chat was used and the app remained open after logout or history deletion. The provided CVE data does not define broader affected product ranges or CPEs. Treat as a targeted remediation item, not an emergency. Prioritize shared Windows machines, support workstations, and environments where TeamViewer chat may carry credentials, customer data, or incident details. Mitigation focus: Check TeamViewer vendor guidance for the fixed version and upgrade accordingly.; Inventory Windows endpoints for TeamViewer desktop 14.3.4730.; Exit TeamViewer completely after sensitive chats until upgraded..
