✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Workaround: Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability. Workaround: Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability. Workaround: To prevent the leakage of OAuth2 bearer tokens, ensure that `.netrc` files are carefully managed. Avoid configuring `.netrc` entries for untrusted or unknown hostnames, particularly when `curl` is used with OAuth2 bearer tokens and is configured to follow redirects. Regularly review and restrict the scope of credentials stored in `.netrc` files to only explicitly trusted destinations.
