CVE-2020-26283: Control character injection in console output in github.com/ipfs/go-ipfs

The vulnerability stems from unescaped control characters in CLI output across multiple command handlers. The GitHub commit diff shows these functions were modified to add EscNonPrint escaping, indicating they previously output user-controlled data without proper sanitization. Each identified function handles user-provided strings (filenames, paths, keys, etc.) and directly passed them to output functions like fmt.Fprintf without escaping, enabling control character injection. The high confidence comes from explicit patching evidence in the commit where escaping was added to these specific output locations.
