MEDIUM 5.4UPGRADE

CVE-2026-27693 is a medium-severity flaw (CVSS 5.4) affecting traccar. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Traccar is an open source GPS tracking system. In org.traccar:traccar versions starting at 6.11.1 before 6.13.0, the KML and GPX export functionality writes device names to XML output without proper escaping. An attacker with low privileges can create a device with a crafted name that injects XML content into exported files. If another user exports and opens the affected KML or GPX file, this can corrupt the file structure and spoof exported loca

traccar traccar UPGRADE

Affected: >= 6.11.1 and < 6.13.0

Fixed in: 6.13.0

Safe to downgrade to: a release before 6.11.1

1. Check installed version

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

2. UPGRADE to 6.13.0 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

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 6.11.1 (Debian / Ubuntu)

apt-cache madison traccar sudo apt install traccar=<VERSION_BEFORE_6.11.1> sudo apt-mark hold traccar

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

dnf --showduplicates list traccar sudo dnf downgrade traccar-<VERSION_BEFORE_6.11.1> sudo dnf versionlock add traccar

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.
