Affected: 4.1

Fixed in: no fixed release known

Safe to downgrade to: a release before 4.1

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 4.1 (Debian / Ubuntu)

apt-cache madison zkeacms sudo apt install zkeacms=<VERSION_BEFORE_4.1> sudo apt-mark hold zkeacms

dnf --showduplicates list zkeacms sudo dnf downgrade zkeacms-<VERSION_BEFORE_4.1> sudo dnf versionlock add zkeacms

Downgrade risk

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