Mitigate without a patch
Close the privilege gap rather than the entry point: audit which accounts, roles and service identities can reach the affected operation, drop the component to the least privilege it actually needs, and review file and directory permissions created by earlier installs — a default left in place is what makes this reachable. Alongside that, restrict the management interface to trusted networks and apply the vendor's recommended configuration mitigations.
