1. Check installed version

apt-cache policy xml-rpc || rpm -q xml-rpc || xml-rpc --version

2. No fixed release: DOWNGRADE to a release before 1.0.2 (Debian / Ubuntu)

apt-cache madison xml-rpc sudo apt install xml-rpc=<VERSION_BEFORE_1.0.2> sudo apt-mark hold xml-rpc

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list xml-rpc sudo dnf downgrade xml-rpc-<VERSION_BEFORE_1.0.2> sudo dnf versionlock add xml-rpc

Downgrade risk

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.
