cargo tree -i libp2p-core(it also shows which of your dependencies pulls it in). - Update within your version requirement:
cargo update -p libp2p-core. If the fix is a newer major or minor than your requirement allows, raise it in Cargo.toml (for examplelibp2p-core = "0.31.1") or update the dependency that pulls it in. - Check again with
cargo audit, or paste your Cargo.lock into our Cargo.toml checker.
Details from the advisory
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.
