The short version

What changed, and why it matters

This commit is a documentation-only changelog update for the Trezor firmware release 2.12.2 and prodtest 0.3.8. It does not change any code, but it lists several security fixes that are part of this release. The most important ones affect Bitcoin and Solana transactions: Bitcoin signing could misidentify external inputs, and replacement transactions (RBF) could silently add new external outputs. Solana token transfers could display the wrong recipient address when using address lookup tables, and some Solana instruction parameters were not shown to the user for confirmation. Because the actual code changes are not in this commit, the risk assessment is based on the vendor's own changelog descriptions.

Recommended action

Treat this as a release-notes commit that announces security fixes shipped elsewhere. Review the actual implementation commits for the four security items (Bitcoin external input, Bitcoin RBF outputs, Solana hidden parameters, Solana ALT recipient) to assess their severity and confirm the fixes. Users should upgrade to firmware 2.12.2 when it is released, especially if they sign Bitcoin or Solana transactions. No immediate action is required solely from this changelog commit.

Security signals we found

01

Bitcoin external input misidentification in signing

02

Bitcoin RBF replacement transaction allows new external outputs

03

Solana hidden instruction parameters not confirmed by user

04

Solana token transfer recipient misdisplayed for ALT addresses

05

Changelog-only commit, no source diff for security fixes

refactor(core): digest EIP-1559/EIP-7702 magic without RLP encoding

This commit is a small internal cleanup in Trezor's Ethereum signing code. It changes how two special 'magic' bytes (the transaction type markers for newer Ethereum transaction formats) are fed into the cryptographic hash. Previously the c…

test(core): test RLP self-encoding bytestrings

This commit only adds a new unit test to the Trezor firmware codebase. It verifies that very short Ethereum RLP-encoded byte strings and small positive integers encode to themselves, which is a known property of the RLP specification. No p…

This commit removes the SHA-1 hashing function from the regular Trezor firmware. SHA-1 is an old, weak hash algorithm that is no longer considered secure for sensitive uses. The change deletes the code that exposes SHA-1 to apps running on…
