CarGurus 12M+ User Records — February 2026

Auto-marketplace CarGurus disclosed a breach affecting more than 12 million users in February 2026.

Auto-marketplace CarGurus disclosed a breach affecting more than 12 million users in February 2026. The exposed dataset includes names, email addresses, vehicle-search history, and some financing-related metadata. Vehicle-search history is more useful for doxxing than it sounds — combined with home address and timing, it can correlate with delivery patterns and routine.
