cakephp cakephp UPGRADE

Affected: >= 5.2.10 and < 5.2.12 · 5.3.0

Fixed in: 5.2.12

Safe to downgrade to: a release before 5.2.10

1. Check installed version

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

2. UPGRADE to 5.2.12 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade cakephp

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 5.2.10 (Debian / Ubuntu)

apt-cache madison cakephp sudo apt install cakephp=<VERSION_BEFORE_5.2.10> sudo apt-mark hold cakephp

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

dnf --showduplicates list cakephp sudo dnf downgrade cakephp-<VERSION_BEFORE_5.2.10> sudo dnf versionlock add cakephp

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.
