The short version

What changed, and why it matters

This commit adds a feature that lets users export their transaction history to a CSV file. The export includes details such as dates, amounts, transaction IDs, addresses, and notes. It is a normal data-export feature, not a code vulnerability. However, because the exported file can contain sensitive financial information, users should be careful where they save or share it. The commit also includes two small safety fixes: it checks whether a screen can be closed before trying to close it, and it clips the share-dialog position on iOS so it does not go off-screen.

Recommended action

Treat this as a feature addition with routine privacy implications rather than a security defect. Reviewers should verify that: (1) exported CSV does not include private keys or seed material, (2) the temp file is reliably deleted after share/save failures, (3) Android scoped storage / MANAGE_EXTERNAL_STORAGE requirements are correctly declared, and (4) user-facing strings inform users that the export contains sensitive data. No immediate patch is required for the code shown.

Security signals we found

01

New data-export surface: transaction history can be written to external storage / shared

02

CSV values are escaped (quote-doubling) before serialization

03

Temp file is written to application documents directory then copied/deleted

04

Android export writes to fixed public Downloads path /storage/emulated/0/Download

05

Share sheet receives file path and filename from app-controlled values

06

Navigator pop guarded with canPop to prevent exception

07

iOS share position origin clipped to screen bounds to avoid PlatformException

08

No input from untrusted sources is parsed or executed
