Developer weekly update February 21, 2024

February 21 2024

Hello developers, and welcome to this week's developer weekly update! In this week's update, we have a very important message about a critical security bug in Agent JS, updates from the NFT working group, and info about ICP at ETHDenver next week! Let's get started.

Critical security vulnerability in Agent JS v1.0.0

A critical security vulnerability in Agent JS versions 1.0.0 and older has been identified and patched. This vulnerability had to do with the agent-js library's Ed25519KeyIdentity.generate function, which generates an ed25519 key pair with the optional parameter to provide a 32 byte seed value. Due to a recent change in agent-js, this function was altered so that when no seed value was provided, the library generated an insecure seed for key pair generation. The resulting principal was a constant identity that was based on an all-zero private key. With this vulnerability, attackers could steal funds associated with this principal on a ledger or compromise access to canisters controlled by this principal.

The patch for the vulnerability is available in agent-js v1.0.1. It is encouraged that all developers upgrade and deploy their canisters immediately.

NFT working group updates

The NFT working group has recently concluded work on the ICRC-7 standard and is looking ahead to the next steps for NFTs on ICP. The group has put together 4 possible new ICRC standards that can be pursued by the working group moving forward:

  • ICRC-8: Ledger markets: This standard would define marketplace standards for fungible or non-fungible ledgers, including the data structures and workflows necessary to support other token standards and achieve atomic trades.

  • ICRC-56: Infinitely scalable multi-canister file system: This standard would define parameters for a standard file system that can be used for storing on-chain NFT media.

  • ICRC-59: Static NFT metadata interface standard: This standard would define a static standard for NFT metadata.

  • ICRC-60: Dynamic NFT metadata interface standard: This standard would define a dynamic standard for NFT metadata.

The NFT working group meets every other Tuesday at 5PM CEST.
