GHSA-9xcg-3q8v-7fq6: gnark commitments to private witnesses in Groth16 as implemented break zero-knowledge property

This report concerns the Groth16 prover when used with commitments (as in `frontend.Committer`). To simplify exposition of the issue, I will focus on the case of a single commitment, to only private witnesses. But the issue should be present whenever commitments are used that include private witnesses. > The commitment to private witnesses `w_i` is computed as ``` c = sum_i w_i * b_i ``` where `b_i` would be `ProvingKey.CommitmentKeys[0].Basis[i]` in the code. While this is a binding commitment, it is not hiding. In practice, an adversary will know the points `b_i`, as they are part of the proving key, and can verify correctness of a guess for the values of `w_i` by computing `c'` as the right hand side of the above formula, and checking whether `c'` is equal to `c`. I attach a proof of concept that demonstrates this. This breaks the perfect zero-knowledge property of Groth16, so the Groth16 scheme using commitments to private witnesses as implemented by gnark fails to be a zk-SNARK...
