thinkphp thinkphp DOWNGRADE

Affected: 5.0.24

Fixed in: no fixed release known

Safe to downgrade to: a release before 5.0.24

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 5.0.24 (Debian / Ubuntu)

apt-cache madison thinkphp sudo apt install thinkphp=<VERSION_BEFORE_5.0.24> sudo apt-mark hold thinkphp

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list thinkphp sudo dnf downgrade thinkphp-<VERSION_BEFORE_5.0.24> sudo dnf versionlock add thinkphp

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.
