Source Advisory Statement

### Impact Control characters are not escaped from console output. This can result in hiding input from the user which could result in the user taking an unknown, malicious action. ### Patches <!-- _Has the problem been patched? What versions should users upgrade to?_ --> - Patched via https://github.com/ipfs/go-ipfs/pull/7831 in v0.8.0 ### For more information If you have any questions or comments about this advisory: * Open an issue in [go-ipfs](http://github.com/ipfs/go-ipfs) * Email us at [security@ipfs.io](mailto:security@ipfs.io)
