Traccar through 6.16.0 contains a weak password recovery vulnerability that allows attackers to reuse password reset tokens as session credentials because TokenManager does not bind tokens to a purpose. Attackers holding a leaked reset link can obtain a full session via /api/session or change passwords via /api/password/update, retaining access for seven days even after the victim resets their password.

Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse".
