Summary

Proof forgery due to insufficient randomness in github.com/consensys/gnark

Details

A a third party may derive a valid proof from a valid initial tuple {proof, public_inputs}, corresponding to the same public inputs as the initial proof. This vulnerability is due to randomness being generated using a small part of the scratch memory describing the state, allowing for degrees of freedom in the transcript. Note that the impact is limited to the PlonK verifier smart contract.
