CVE-2026-41506 (opens in a new tab)How to fix?
Upgrade github.com/go-git/go-git/v5/plumbing/transport/http to version 5.18.0 or higher.
Overview
Affected versions of this package are vulnerable to Insufficiently Protected Credentials in the advertisedReferences() function. The headers - including Authorization headers - from an initial /info/refs request are forwarded to redirect targets. An attacker can obtain authentication credentials by controlling a redirect target, and those credentials may be reused on other endpoints or attempted against other repositories owned by the victim. This is only exploitable if the client interacts with untrusted or misconfigured remote servers, or uses HTTP (not HTTPS) connections.
