    Uncaught Exception

    @libp2p/webrtc is an A libp2p transport using WebRTC connections

    Affected versions of this package are vulnerable to Uncaught Exception via the STUN listener in stun-listener.ts, where an unvalidated ufrag value from an incoming STUN request is passed directly into the native ICE stack as both the ICE username fragment and password. Because the ufrag is reused as icePwd without checking that it satisfies RFC 8445 ICE credential requirements, a remote attacker can send a STUN request carrying a malformed ufrag value that causes the native ICE stack to abort, crashing the WebRTC-direct listener process.

    How to fix Uncaught Exception?

    Upgrade @libp2p/webrtc to version 6.0.28 or higher.
