Doc Text:
A flaw was found in Traccar. This vulnerability allows an unauthenticated remote attacker to cause unauthorized information disclosure by accessing protected device media files. Due to inconsistent request path handling between security filters and the underlying web server, an attacker who knows or guesses a device identifier and file name can bypass authorization checks by inserting semicolon characters into request paths.

Description OSIDB Bzimport 2026-11-05 22:03:58 UTC 
Traccar is an open source GPS tracking system. From 5.1 until 6.15.0, WebModule.java's MediaFilter Guice mapping and WebServer.java's Jetty ResourceServlet assign different routing meanings to path parameters at /api/media/*. An unauthenticated attacker who knows or guesses a device unique ID and media filename can insert a semicolon at the Servlet boundary, bypass MediaFilter's session and device authorization checks, and retrieve the protected media because Jetty still dispatches the noncanonical path to ResourceServlet. The demonstrated impact is read-only disclosure of a protected device media file; depending on the deployment and stored media, this could expose photographs, audio, video, or other uploaded files. The advisory does not establish directory listing, traversal, modification, account takeover, denial of service, or code execution. Reverse proxies that reject or rewrite semicolon path parameters may block the request. This issue is fixed in version 6.15.0.
