A bug has been found in TeamViewer for Linux before 15.28, that could result in an inadvertent re-use of a previously used connection password after a process crash. The bug has been fixed with version 15.28. We recommend updating your Linux client installations at the earliest convenience.
Update to the latest version (15.28 or higher)
For users leveraging passwordless authentication (“Easy Access”) and/or MFA for connections the issue is not exploitable.
