Problem
decode_invocation_paramsdecoded the expected SCALE parameters but did not require them to consume the full invocation payload. A valid parameter prefix followed by extra bytes was therefore accepted.Fix
Use
DecodeAllafter validating the Sails header so invocation parameters must consume every remaining byte. Add regression coverage proving valid payloads still decode and trailing bytes are rejected.Verification
