CVE-2026-108737

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.
