Vulnerability Data
go-git is an extensible git implementation library written in pure Go. Prior to versions 5.18.0 and 6.0.0-alpha.2, go-git may leak HTTP authentication credentials when following redirects during smart-HTTP clone and fetch operations. This issue has been patched in versions 5.18.0…

Mitigating Controls (NIST 800-53 r5) AI
Directly requires applying the vendor patch that eliminates the redirect-based credential leak in go-git.
Mandates secure authenticator handling and transmission rules that would have prevented credentials from being sent on cross-origin redirects.
Requires cryptographic protection and integrity of information in transit, addressing the exposure of HTTP auth headers during clone/fetch redirects.

Encrypting data-at-rest fully prevents insecure credential storage while only partially satisfying the broader data-protection outcome.
Encrypting data-in-transit fully prevents interception of credentials in motion while only partially satisfying the broader data-protection outcome.
Credential management practices directly reduce insecure storage/transmission but do not guarantee encryption or transport protection.
Protecting identity assertions covers conveyance of credentials but is narrower than full credential lifecycle protection.
Authentication policies can enforce stronger credential handling yet address only verification, not storage or transit protection.

Requiring protected storage, transmission, and non-display of passwords prevents credentials from being stored or sent in clear text where they can be harvested by unauthorized actors.
Protecting secret and private keys against disclosure and unauthorized use decreases the exposure of credentials that are stored or transmitted in recoverable form.
Forbidding clear-text transmission and display of passwords, plus the use of stronger alternatives to passwords, prevents credentials from being obtained or reused by attackers.
Acceptable-use expectations that cover protection of credentials and information assets throughout their lifecycle discourage practices that expose or mishandle authentication material.
Contractual clauses that survive termination help ensure that credentials and other secrets are not retained or misused after employment ends.
Regular reminders about password security and personal accountability make users less likely to store or transmit credentials in cleartext or other unprotected forms.
