✅ Remediation

For details on how to apply this update, refer to: https://docs.redhat.com/en/documentation/openshift_container_platform/latest/html/operators/administrator-tasks#olm-upgrading-operators Workaround: To mitigate this issue, restrict the processing of untrusted or unvalidated XPath expressions by applications which utilize the `github.com/antchfx/xpath` component. Implement input validation and sanitization for all XPath expressions originating from external or untrusted sources. If possible, configure applications to only process XPath expressions from trusted sources or disable features that allow arbitrary XPath expression evaluation. 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 mitigate this vulnerability, limit the use of multiple sequential optional groups in route patterns within applications that use `path-to-regexp`. Additionally, avoid directly passing user-controlled input as route patterns to prevent the generation of maliciously crafted regular expressions. Workaround: To mitigate this issue, implement infrastructure-level normalization to ensure all incoming HTTP/2 `:path` headers are properly formatted with a leading slash before reaching the gRPC-Go server. This can be achieved by configuring a reverse proxy or API gateway to validate and normalize the `:path` header. Ensure that any such intermediary is properly configured and restarted to apply the changes, which may temporarily impact service availability.
