Description

This package has been moved to github.com/ipfs/boxo/bitswap, this vulnerability is tracked there: https://github.com/ipfs/boxo/security/advisories/GHSA-m974-xj4j-7qv5 (CVE-2023-25568)

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/go-bitswap@v0.12.0, this will replace the go-bitswap implementation by stubs which points to boxo.
  2. Open https://github.com/ipfs/boxo/security/advisories/GHSA-m974-xj4j-7qv5 and then follow boxo's remediation section.

Workarounds

If you are using the stubs at github.com/ipfs/go-bitswap and not taking advantage of the features provided by the server, refactoring your code to use the new split API will allows you to run in a client-only mode using: github.com/ipfs/go-bitswap/client.
