CVE-2026-108738 Details
Description
Traccar 5.7 through 6.16.0 contains a cross-site request forgery vulnerability that allows attackers to log victims into attacker-controlled accounts because the OpenID Connect callback never validates the OAuth state parameter. Attackers can induce a victim's browser to load /api/session/openid/callback with their own authorization code, causing data the victim enters, such as registered devices, to land in the attacker's account.
A cross-site request forgery (CSRF) vulnerability has been identified in Traccar versions 5.7 through 6.16.0. This vulnerability allows attackers to log victims into accounts controlled by the attackers. The issue arises because the OpenID Connect callback does not validate the OAuth state parameter. Attackers can exploit this by inducing a victim's browser to load the callback endpoint with an authorization code belonging to the attacker, resulting in the victim inadvertently transferring data, such as registered devices, to the attacker's account.
Users are advised to update to Traccar version 6.16.1 or later, where this vulnerability has been addressed.
