    Issue
    An issue was discovered in the ark-r1cs-std crate before 0.3.1 for Rust. It does not enforce any constraints in the FieldVar::mulbyinverse method. Thus, a prover can produce a proof that is unsound but is nonetheless verified.

    Recommended action: Upgrade to 0.3.1 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
