CVE-2021-28681

low-risk
Published 2021-03-18

Pion WebRTC before 3.0.15 didn't properly tear down the DTLS Connection when certificate verification failed. The PeerConnectionState was set to failed, but a user could ignore that and continue to use the PeerConnection. )A WebRTC implementation shouldn't allow the user to continue if verification has failed.)

Do I need to act?
