Remediation

This is a two step process:

1. Apply one of:
   • (recommended) upgrade from github.com/ipfs/go-bitswap to github.com/ipfs/boxo/bitswap.
   • If you are still using github.com/ipfs/go-bitswap and cannot upgrade to boxo, you can upgrade to github.com/ipfs/[email protected], this will replace the go-bitswap implementation by stubs which points to boxo.
2. Open GHSA-m974-xj4j-7qv5 and then follow boxo’s remediation section.
