✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Workaround: Disable interceptors.retry() for untrusted upstreams, or set maxRetries: 0 on the retry interceptor configuration. Alternatively, remove or recalculate the Content-Length header before forwarding a response body assembled by undici to downstream HTTP/1.1 peers. 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.
