Inability to cancel certain flows on pre-production firmware

報告日:October 31, 2025

In a pre-production firmware for Trezor Safe 7, a user could enter a dialog where pressing Cancel did not actually cancel the flow. This issue occurred only in non-critical paths such as staking delegation or similar actions, not in fund-sending flows.

The issue was present only in a pre-production firmware that was available for small group of people directly after the launch of Safe 7. The fix was already included in the version released to the general public.
