Mitigation checklist

Recommended fix / mitigation

For affected community projects where the `rabbitmq_trust_store` plugin is enabled, disable the plugin if it is not essential for operations. If the plugin is required, ensure that whitelisted certificates are managed securely and their Issuer DN and serial numbers are not publicly exposed or easily guessable.
