Traccar: >> Traccar >> 6.11.1 Security Vulnerabilities
Traccar is an open source GPS tracking system. Prior to 6.13.0, DeviceResource.uploadImage authorizes the target device only through Condition.Permission(User.class, getUserId(), Device.class) and then immediately streams the uploaded body into mediaManager.createFileStream(...). Unlike the generic mutation path in BaseObjectResource.update and the explicit device mutation handler updateAccumulators, this route never invokes permissionsService.checkEdit(getUserId(), Device.class, false, false). The skipped guard is exactly where Traccar enforces readonly and deviceReadonly restrictions for non-admin users. An unauthorized user can replace a device’s stored image file under the server media directory. This allows modification of UI-visible device media and any downstream workflows that rely on the persisted image, despite other device update paths correctly rejecting the same identity. This vulnerability is fixed in 6.13.0.

Traccar is an open source GPS tracking system. 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. This issue is fixed in version 6.13.0.

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.

Traccar is an open source GPS tracking system. In versions between 6.11.1 and 6.13.0, the CSV export functionality writes position data, including user-controlled device and computed attributes, to CSV output without proper escaping. An attacker can inject spreadsheet formulas through exported fields. When a manager or administrator opens the exported CSV file in spreadsheet software, this can cause formula execution and lead to command execution or data exfiltration. This has been patched in version 6.13.0.

Versions of the Traccar open-source GPS tracking system up to and including 6.11.1 contain an issue in which authenticated users can steal OAuth 2.0 authorization codes by exploiting an open redirect vulnerability in two OIDC-related endpoints. The `redirect_uri` parameter is not validated against a whitelist, allowing attackers to redirect authorization codes to attacker-controlled URLs, enabling account takeover on any OAuth-integrated application. As of time of publication, it is unclear whether a fix is available.

Versions of the Traccar open-source GPS tracking system starting with 6.11.1 contain an issue in which authenticated users can execute arbitrary JavaScript in the context of other users' browsers by uploading malicious SVG files as device images. The application accepts SVG file uploads without sanitization and serves them with the `image/svg+xml` Content-Type, allowing embedded JavaScript to execute when victims view the image. As of time of publication, it is unclear whether a fix is available.

Versions of the Traccar open-source GPS tracking system up to and including 6.11.1 contain an issue in which authenticated users who can create or edit devices can set a device `uniqueId` to an absolute path. When uploading a device image, Traccar uses that `uniqueId` to build the filesystem path without enforcing that the resolved path stays under the media root. This allows writing files outside the media directory. As of time of publication, it is unclear whether a fix is available.

Versions of the Traccar open-source GPS tracking system up to and including 6.11.1 contain a Cross-Site WebSocket Hijacking (CSWSH) vulnerability in the `/api/socket` endpoint. The application fails to validate the `Origin` header during the WebSocket handshake. This allows a remote attacker to bypass the Same Origin Policy (SOP) and establish a full-duplex WebSocket connection using a legitimate user's credentials (JSESSIONID). As of time of publication, it is unclear whether a fix is available.
