Impact
go-gitmay leak HTTP authentication credentials when following redirects during smart-HTTP clone and fetch operations.If a remote repository responds to the initial
/info/refsrequest with a redirect to a different host, go-git updates the session endpoint to the redirected location and reuses the original authentication for subsequent requests. This can result in the credentials (e.g. Authorization headers) being sent to an unintended host.An attacker controlling or influencing the redirect target can capture these credentials and potentially reuse them to access the victim’s repositories or other resources, depending on the scope of the credential.
Clients using
go-gitexclusively with trusted remotes (for example, GitHub or GitLab), and over a secure HTTPS connection, are not affected by this issue. The risk arises when interacting with untrusted or misconfigured Git servers, or when using unsecured HTTP connections, which is not recommended. Such configurations also expose clients to a broader class of security risks beyond this issue, including credential interception and tampering of repository data.Patches
Users should upgrade to
v5.18.0, orv6.0.0-alpha.2, in order to mitigate this vulnerability. Versions prior to v5 are likely to be affected, users are recommended to upgrade to a supportedgo-gitversion.The patched versions add support for configuring followRedirects. In line with upstream behaviour, the default is now
initial, while users can opt intoFollowRedirectsorNoFollowRedirectsprogrammatically.Credit
