Security bulletins

A critical priority is assigned to a problem that touches a core function of TeamViewer’s software or services, and that could have a critical impact on your security posture (such as a RCE vulnerability “in the wild”). We recommend following our communication closely and implementing all advised measures. This will likely include an immediate update of the TeamViewer client.

An important priority is assigned to a problem of TeamViewer’s software or services that could significantly impair your security posture (such as a privilege escalation vulnerability easy to reproduce). We recommend implementing all advised measures. This will likely include an immediate update of the TeamViewer client.

A moderate priority is assigned to a problem of TeamViewer’s software or services that could impair your local security posture only under specific circumstances. We recommend implementing all advised measures. This will likely include an update of the TeamViewer client at the earliest convenience.

A low priority is assigned to a problem that is unlikely to be reproduced and requires privileged local access to be exploited. We recommend implementing all advised measures. This will likely include an update of the TeamViewer client during the next update cycle. The low priority category also includes general security-related announcements by TeamViewer.
