How to Fix GHSA-9xfq-8j3r-xp5g

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

github.com/Consensys/gnark-crypto fixed: 0.12.0 
Upgrade github.com/Consensys/gnark-crypto to 0.12.0
github.com/consensys/gnark-crypto fixed: 0.12.0 
Upgrade github.com/consensys/gnark-crypto to 0.12.0
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 github.com/Consensys/gnark-crypto

How to Check if You Are Affected

To determine whether your application is affected by GHSA-9xfq-8j3r-xp5g, inspect your project dependencies for Duplicate Advisory:

inspect dependencies for github.com/Consensys/gnark-crypto

Analyze the terminal output to locate any version of Duplicate Advisory in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.12.0), 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-502: Deserialization of Untrusted Data, where the product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid. In Duplicate Advisory, 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

## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-fr8m-434r-g3xp. This link is maintained to preserve external references. ## Original Description Consensys gnark-crypto through 0.11.2 allows Signature Malleability. This occurs because deserialisation of EdDSA and ECDSA signatures does not ensure that the data is in a certain interval.
