CVE-2025-61666Public exploitNetwork attack vector

Unauthenticated file disclosure via backslash path traversal

Published Oct 2, 2025 · Updated Oct 2, 2025

Path traversal in Traccar Server 5.8 through 6.8.1 on Windows allows remote attackers to read arbitrary local files without authentication. DefaultOverrideServlet passes the request path directly to Jetty Resource.addPath, whose canonicalization accepts Windows backslash traversal sequences. The web.override setting is required; it is enabled by default in 6.1 through 6.8.1 but must be configured in 5.8 through 6.0.
