CVE-2026-41506 is a vulnerability in the go-git library, which is an extensible Git implementation for Go. The issue arises when go-git follows HTTP redirects during smart-HTTP clone and fetch operations, potentially exposing sensitive HTTP authentication credentials to an attacker controlling the redirect target. Red Hat has rated this flaw as Moderate impact because exploitation requires user interaction and control of the redirect target. The vulnerability is classified under CWE-601 (URL Redirection to Untrusted Site). The affected package in Red Hat Hardened Images is syft version 1.44.0-0.3.hum1 for aarch64 and x86_64 architectures. Red Hat has not released a fix for this issue yet and states that mitigation options are either unavailable or unsuitable for widespread deployment.

The vulnerability can lead to the disclosure of HTTP authentication credentials during Git operations involving redirects. This could allow an attacker to capture sensitive credentials if the user interacts with a malicious repository or redirect chain. However, the vulnerability does not enable code execution, privilege escalation, or direct system compromise. The impact is limited to confidentiality loss of authentication credentials only.

Currently, Red Hat does not provide an official fix or patch for this vulnerability. Mitigation options are either unavailable or do not meet Red Hat's criteria for ease of use, deployment, or applicability. Users should avoid interacting with untrusted or suspicious Git repositories that might exploit this redirect behavior. Monitor Red Hat advisories for future updates or patches addressing this issue.
