SCA: security update for @bsv/wallet-toolbox, @bsv/wallet-toolbox-client, @bsv/wallet-toolbox-mobile (GHSA-36f9-7rg5-cpf8)

high Tenable Cloud Security Plugin ID 448359

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - `@bsv/wallet-toolbox` provides BRC-100 wallet signing and storage components, while `@bsv/wallet-toolbox-
 client` and `@bsv/wallet-toolbox-mobile` provide client-focused distributions for standard and mobile
 applications using wallet storage services. A vulnerability in these packages causes transactions created
 through a remote `StorageClient` to trust output locking scripts returned by the storage provider without
 verifying that they match the outputs requested by the caller. A malicious or compromised storage provider
 can substitute a recipient script or inject an additional output, causing the wallet to sign and broadcast
 a transaction that redirects funds while the application and user interface continue to display the
 intended recipient. Source and npm publication history indicate that stable versions `@bsv/wallet-toolbox`
 and `@bsv/wallet-toolbox-client` from 1.1.47 through 2.3.3, and `@bsv/wallet-toolbox-mobile` from its
 initial 1.3.21 release through 2.3.3, are affected. All three packages are patched in version 2.4.0.
 Applications unable to upgrade should avoid remote `StorageClient` providers, use local storage, or
 independently verify every transaction output’s locking script and value against the original request
 before signing (CVE-2026-56744)

Solution

Update the @bsv/wallet-toolbox library and its related packages to version 2.4.0 or later.
