Bumps @metamask/utils from 11.11.0 to 12.0.0.

Release notes

Sourced from @​metamask/utils's releases.

12.0.0

Changed

  • BREAKING: Bump TypeScript target to ES2022 (#333)
    • This package now ships ES2022 code, requiring a compatible modern environment or bundler configuration to consume.
  • BREAKING: Drop support for Node 18 and 20 (#328)
  • BREAKING: Drop CommonJS support (#9536)
    • This package is now ESM-only, but can still be used in CommonJS projects via require(esm) in modern Node.js versions (22+), or dynamic imports in older Node.js versions.
  • Bump @ethereumjs/tx from ^4.2.0 to ^5.4.0 (#321)
    • The deprecated Keyring.signTransaction now returns LegacyTxData rather than TxData. These describe the same shape: @ethereumjs/tx@5 repurposed the name TxData for a map keyed by transaction type and renamed the old meaning to LegacyTxData. Implementations do not need changing.
  • Bump @metamask/scure-bip39 from ^2.0.3 to ^2.1.1 (#311)
  • Bump @metamask/superstruct from ^3.1.0 to ^3.4.1 (#311)
  • Bump @noble/hashes from ^1.3.1 to ^1.8.0 (#311)
  • Bump @scure/base from ^1.1.3 to ^1.2.6 (#311)
  • Bump semver from ^7.5.4 to ^7.6.3 (#311)

11.12.1

Fixed

  • Fix ESM compatibility for the BIP-39 mnemonic utilities (#309)

11.12.0

Added

  • Add uint8ArrayToMnemonic and convertMnemonicToWordlistIndices utilities (#300)
    • uint8ArrayToMnemonic converts little-endian Uint16 English BIP-39 wordlist indices into a mnemonic string.
    • convertMnemonicToWordlistIndices converts a mnemonic string into little-endian Uint16 wordlist indices encoded as a Uint8Array.
  • Add @metamask/scure-bip39 as a dependency (#300)
  • Add optimized sha512 and sha384 utility functions (#305)

Network access: npm @ethereumjs/util in module globalThis["fetch"]

Module: globalThis["fetch"]

Location: Package overview

From: package.json → npm/@metamask/utils@12.0.0 → npm/@ethereumjs/util@9.1.0

ℹ Read more on: This package | This alert | What is network access?

Next steps: Take a moment to review the security alert above. Review the linked package source code to understand the potential risk. Ensure the package is not malicious before proceeding. If you're unsure how to proceed, reach out to your security team or ask the Socket team for help at support@socket.dev.

Suggestion: Packages should remove all network access that is functionally unnecessary. Consumers should audit network access to ensure legitimate use.

Mark the package as acceptable risk. To ignore this alert only in this pull request, reply with the comment @SocketSecurity ignore npm/@ethereumjs/util@9.1.0. You can also ignore all packages with @SocketSecurity ignore-all. To ignore an alert for all future pull requests, use Socket's Dashboard to change the triage state of this alert.
