CVE-2026-27694
Medium
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.
