CVE-2024-8253: The Post Grid and Gutenberg Blocks plugin for WordPress is vulnerable to privilege escalation in all versions

This week

HIGH 8.8UPGRADE

CVE-2024-8253 is a high-severity flaw (CVSS 8.8) affecting post grid. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

The Post Grid and Gutenberg Blocks plugin for WordPress is vulnerable to privilege escalation in all versions 2.2.87 to 2.2.90. This is due to the plugin not properly restricting what user meta values can be updated and ensuring a form is active. This makes it possible for authenticated attackers, with subscriber-level access and above, to update their user meta to become an administrator.

pickplugins post grid UPGRADE

Affected: >= 2.2.87 and < 2.2.91

Fixed in: 2.2.91

Safe to downgrade to: a release before 2.2.87

1. Check installed version

apt-cache policy post-grid || rpm -q post-grid || post-grid --version

sudo apt update && sudo apt install --only-upgrade post-grid

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 2.2.87 (Debian / Ubuntu)

apt-cache madison post-grid sudo apt install post-grid=<VERSION_BEFORE_2.2.87> sudo apt-mark hold post-grid

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

dnf --showduplicates list post-grid sudo dnf downgrade post-grid-<VERSION_BEFORE_2.2.87> sudo dnf versionlock add post-grid

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.
