3. If no update is available yet, DOWNGRADE to a release before 3.0.0

npm view payload versions npm install payload@"<3.0.0"

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
