Fixed in: no fixed release known

Safe to downgrade to: a release before 1.9c

1. Check installed version

apt-cache policy nedi || rpm -q nedi || nedi --version

2. No fixed release: DOWNGRADE to a release before 1.9c (Debian / Ubuntu)

apt-cache madison nedi sudo apt install nedi=<VERSION_BEFORE_1.9c> sudo apt-mark hold nedi

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.
