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.
