Received Received - Intake
Open Redirect in Traccar OIDC Enables OAuth Code Theft

Publication date: 2026-02-23

Last updated on: 2026-02-26

Assigner: GitHub, Inc.

Description
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.

Executive Summary

This vulnerability affects versions of the Traccar open-source GPS tracking system up to and including 6.11.1. It involves an open redirect issue in two OpenID Connect (OIDC)-related endpoints where the `redirect_uri` parameter is not validated against a whitelist. Authenticated users can exploit this flaw to steal OAuth 2.0 authorization codes by redirecting them to attacker-controlled URLs.

By stealing these authorization codes, attackers can potentially take over accounts on any OAuth-integrated application that relies on Traccar for authentication.

Impact Analysis

The vulnerability can lead to account takeover on OAuth-integrated applications. Attackers who exploit the open redirect flaw can steal authorization codes and use them to gain unauthorized access to user accounts.

This can result in unauthorized access to sensitive location data tracked by the Traccar system or any other linked services, potentially compromising user privacy and security.
