2. No fixed release: DOWNGRADE to a release before 6.x-2.0 (Debian / Ubuntu)

apt-cache madison hashcash sudo apt install hashcash=<VERSION_BEFORE_6.x-2.0> sudo apt-mark hold hashcash

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

dnf --showduplicates list hashcash sudo dnf downgrade hashcash-<VERSION_BEFORE_6.x-2.0> sudo dnf versionlock add hashcash

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.
