Fixed in: no fixed release known

Safe to downgrade to: a release before 2023

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 2023 (Debian / Ubuntu)

apt-cache madison coldfusion sudo apt install coldfusion=<VERSION_BEFORE_2023> sudo apt-mark hold coldfusion

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

dnf --showduplicates list coldfusion sudo dnf downgrade coldfusion-<VERSION_BEFORE_2023> sudo dnf versionlock add coldfusion

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.

Exact fixes by distribution

A distro patch exists: prefer upgrading over downgrading.
