SCA: security update for bsv-sdk, bsv-wallet (GHSA-hc36-c89j-5f4j)

high Tenable Cloud Security Plugin ID 440134

Description

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

- BSV Ruby SDK is the Ruby SDK for the BSV blockchain. From 0.3.1 to before 0.8.2,
BSV::Wallet::WalletClient#acquire_certificate persists certificate records to storage without verifying
the certifier's signature over the certificate contents. In acquisition_protocol: 'direct', the caller
supplies all certificate fields (including signature:) and the record is written to storage verbatim. In
acquisition_protocol: 'issuance', the client POSTs to a certifier URL and writes whatever signature the
response body contains, also without verification. An attacker who can reach either API (or who controls a
certifier endpoint targeted by the issuance path) can forge identity certificates that subsequently appear
authentic to list_certificates and prove_certificate. (CVE-2026-40070)

Solution

Update the bsv-wallet library and its related packages to version 0.3.4 or later.
