Nothing in the “core” bitcoin protocol involves a Diffie-Hellman key exchange, so there is no real surface area for such an attack (at least where funds are concerned).

It would be a problem if you had funds derived from a private key that you used in a key-exchange for a messaging protocol where you’re not verifying your peer’s provided pubkey.

If you’re using a seed + HD wallet, make sure your comms keys are on a different, distinct derivation path from your funds keys.

Note that this is going to be wallet implementation details, and probably not easy to verify as a consumer.
