Fixed in: 14.14.1, 23.6.7, 24.9.10, 25.0.4

Safe to downgrade to: a release before 14.2.0

1. Check installed version

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

2. UPGRADE to 14.14.1 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade vaadin

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade vaadin

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 14.2.0 (Debian / Ubuntu)

apt-cache madison vaadin sudo apt install vaadin=<VERSION_BEFORE_14.2.0> sudo apt-mark hold vaadin

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list vaadin sudo dnf downgrade vaadin-<VERSION_BEFORE_14.2.0> sudo dnf versionlock add vaadin

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.
