How to Fix GHSA-rm66-9gh4-4gp8

To remediate this vulnerability, upgrade all affected Cggmp21 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

cggmp21 fixed: 0.4.0 
Upgrade cggmp21 to 0.4.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for cggmp21

How to Check if You Are Affected

To determine whether your application is affected by GHSA-rm66-9gh4-4gp8, inspect your project dependencies for Cggmp21:

inspect dependencies for cggmp21

Analyze the terminal output to locate any version of Cggmp21 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.4.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-327: Use of a Broken or Risky Cryptographic Algorithm, where the product uses a broken or risky cryptographic algorithm or protocol. In Cggmp21, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Challenge derivation in non-interactive ZK proofs was ambiguous and that could lead to security vulnerability (however, it's unknown if it could be exploited).
