Affected: < 3.6.11 · >= 4.0.0 and < 4.1.6 · 4.2.0

Fixed in: 3.6.11, 4.1.6

Safe to downgrade to: a release before 4.0.0

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

2. UPGRADE to 3.6.11 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade cxf

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 4.0.0 (Debian / Ubuntu)

apt-cache madison cxf sudo apt install cxf=<VERSION_BEFORE_4.0.0> sudo apt-mark hold cxf

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

dnf --showduplicates list cxf sudo dnf downgrade cxf-<VERSION_BEFORE_4.0.0> sudo dnf versionlock add cxf

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.
