GeoServer is an open source server that allows users to share and edit geospatial data. From version 2.26.0 to before 2.26.2 and before 2.25.6, an XML External Entity (XXE) vulnerability was identified. The application accepts XML input through a specific endpoint /geoserver/wms operation GetMap. However, this input is not sufficiently sanitized or restricted, allowing an attacker to define external entities within the XML request. This issue has

geoserver geoserver UPGRADE

Affected: < 2.25.6 · >= 2.26.0 and < 2.26.2

Fixed in: 2.25.6, 2.26.2

Safe to downgrade to: a release before 2.26.0

1. Check installed version

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

2. UPGRADE to 2.25.6 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade geoserver

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 2.26.0 (Debian / Ubuntu)

apt-cache madison geoserver sudo apt install geoserver=<VERSION_BEFORE_2.26.0> sudo apt-mark hold geoserver

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

dnf --showduplicates list geoserver sudo dnf downgrade geoserver-<VERSION_BEFORE_2.26.0> sudo dnf versionlock add geoserver

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.
