Fixed in: no fixed release known

Safe to downgrade to: a release before 7.0.3

1. Check installed version

apt-cache policy engineering-lifecycle-management || rpm -q engineering-lifecycle-management || engineering-lifecycle-management --version

2. No fixed release: DOWNGRADE to a release before 7.0.3 (Debian / Ubuntu)

apt-cache madison engineering-lifecycle-management sudo apt install engineering-lifecycle-management=<VERSION_BEFORE_7.0.3> sudo apt-mark hold engineering-lifecycle-management

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

dnf --showduplicates list engineering-lifecycle-management sudo dnf downgrade engineering-lifecycle-management-<VERSION_BEFORE_7.0.3> sudo dnf versionlock add engineering-lifecycle-management

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.
