wordpress wordpress UPGRADE

Affected: >= 6.9 and < 6.9.5 · >= 7.0 and < 7.0.2

Fixed in: 6.9.5, 7.0.2

Safe to downgrade to: a release before 6.9

1. Check installed version

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

2. UPGRADE to 6.9.5 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade wordpress

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 6.9 (Debian / Ubuntu)

apt-cache madison wordpress sudo apt install wordpress=<VERSION_BEFORE_6.9> sudo apt-mark hold wordpress

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

dnf --showduplicates list wordpress sudo dnf downgrade wordpress-<VERSION_BEFORE_6.9> sudo dnf versionlock add wordpress

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.
