A critical cryptographic vulnerability has been identified in the `dispatch_contract.py` module, where the HMAC envelope signing mechanism fails to incorporate the `payload` field into its canonical signing input. The flaw, located at lines 107–123 in the `_sign_envelope_payload` function, signs only metadata fields—`a...

A security researcher has raised concerns over the use of `scalarmult` output directly as a shared cryptographic key in a three-party communication scheme, warning that this approach contradicts established best practices documented in the official libsodium documentation.
The issue centers on a implementation that de...
