Two-factor authentication bypass in TeamViewer Full Client and Host for macOS before 15.80 lets an already-authenticated, high-privileged attacker circumvent the configured 2FA 'Connections approval' control on the Unattended Access feature and establish a full remote session to the target Mac. The flaw is a business-logic error in the connection-approval flow (CWE-288) rather than a memory-safety issue, and successful exploitation yields interactive control of the host. No public exploit code has been identified at time of analysis and the issue is not listed in CISA KEV.
