Overview

CVE-2026-27694 is a medium-severity vulnerability. It was published on May 5, 2026 and has a CVSS 3.1 base score of 5.4 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.4, rated MEDIUM. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

Traccar is an open source GPS tracking system. In org.traccar:traccar versions starting at 6.11.1 before 6.13.0, the email notification templates insert user-controlled device, geofence, and driver names into HTML email output without proper escaping. An attacker with low privileges can store crafted HTML in these fields, which is then rendered in notification emails sent to other users with access to the affected devices. This can lead to phishing or spoofed email content. This issue is fixed in version 6.13.0.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
