- CWE-352
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.
