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","state":0,"publishedAt":"2026-09-24T17:17:05.047+00:00","modifiedAt":"2026-09-30T19:57:08.043+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":8.7,"severity":"HIGH"}],"references":["https://github.com/bsv-blockchain/ts-stack/commit/3a11f6111919245a3090e9f3895cfc4f21a80d28","https://github.com/bsv-blockchain/ts-stack/commit/5492cabbef4ddc7f60cc49cdf5d8c74ed2e5d949","https://github.com/bsv-blockchain/ts-stack/commit/5ee60395e78e8b822d9a78efeacc6039c249819b","https://github.com/bsv-blockchain/ts-stack/security/advisories/GHSA-36f9-7rg5-cpf8","https://github.com/bsv-blockchain/wallet-toolbox/commit/ca651b067c0238cd8b1ddd3af225daa503857a07"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-56744","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-1288"],"productCriteria":[],"sourceDates":{"published":"2026-09-24T17:17:05.047","lastModified":"2026-09-30T19:57:08.043"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
