How to Fix GHSA-wc36-xgcc-jwpr

To remediate this vulnerability, upgrade all affected Libp2p core dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

libp2p-core fixed: 0.30.2 
Upgrade libp2p-core to 0.30.2
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 libp2p-core

How to Check if You Are Affected

To determine whether your application is affected by GHSA-wc36-xgcc-jwpr, inspect your project dependencies for Libp2p core:

inspect dependencies for libp2p-core

Analyze the terminal output to locate any version of Libp2p core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.30.2), 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 General Security Weakness. In Libp2p core, 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

Affected versions of this crate did not check that the public key the signature was created with matches the peer ID of the peer record. Any combination was considered valid. This allows an attacker to republish an existing `PeerRecord` with a different `PeerId`.
