The short version

What changed, and why it matters

This update fixes three small but real bugs in the COLDCARD's Notes & Passwords feature. The most important fix corrects a reversed menu setting: the 'Send Password' option was accidentally shown only when USB was disabled, and hidden when USB was enabled. It also prevents the device from storing a blank password as the special value 'None', which could crash the device later when sending a password. Finally, it stops a misleading 'Saving...' message from appearing after a failed import.

Recommended action

No immediate user action beyond applying the firmware update is needed. The bugs are functional UX/crash issues rather than remote-exploitable vulnerabilities. Users who created password entries while cancelling the password prompt should verify those entries after updating.

Security signals we found

01

Reversed access-control predicate caused a security-sensitive action ('Send Password') to be available in the wrong configuration state

02

None value stored for a password field led to an unhandled TypeError/crash when the 'Send Password' feature was used

03

Post-failure success UX could mislead users about whether an import succeeded
