✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 Workaround: To mitigate this issue, implement strict input validation before passing any property paths to the _.unset and _.omit functions to block attempts to access the prototype chain. Ensure that strings like __proto__, constructor and prototype are blocked, for example. 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.
