# Changelog

## v0.6.3
* Use `paillier-zk v0.4.3` that has patched ZK proof which includes a missing check

> [!WARNING]  
> This library version implements CGGMP21 which uses Zero-Knowledge proofs as defined the CGGMP21
> paper, which contains a critical vulnerability that could lead to full private key recovery.
> 
> While we have patched this specific high-severity issue, ZK proofs still lacks other important
> security checks introduced in the revised CGGMP24 paper. The absence of these checks may expose
> other security risks.
> 
> For complete protection, please upgrade to the CGGMP24.
