Lifecycle Timeline
3DescriptionGitHub Advisory
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.
AnalysisAI
Traccar GPS tracking system through version 6.11.1 allows authenticated users to hijack OAuth 2.0 authorization codes through unvalidated redirect URIs in OIDC endpoints, enabling account takeover on integrated applications. The vulnerability stems from missing whitelist validation on the redirect_uri parameter, permitting attackers to exfiltrate authorization codes to attacker-controlled servers. Public exploit code exists for this HIGH severity flaw, and no patch is currently available.
