ajax30 bravecms UPGRADE

Affected: >= 2.0.0 and < 2.0.6

Fixed in: 2.0.6

Safe to downgrade to: a release before 2.0.0

1. Check installed version

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

2. UPGRADE to 2.0.6 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

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 2.0.0 (Debian / Ubuntu)

apt-cache madison bravecms sudo apt install bravecms=<VERSION_BEFORE_2.0.0> sudo apt-mark hold bravecms

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

dnf --showduplicates list bravecms sudo dnf downgrade bravecms-<VERSION_BEFORE_2.0.0> sudo dnf versionlock add bravecms

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.
