How to Fix GHSA-84c3-j8r2-mcm8

To remediate this vulnerability, upgrade all affected @nfid/embed dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

@nfid/embed fixed: 0.10.1-alpha.6 
npm install @nfid/embed@0.10.1-alpha.6
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls @nfid/embed

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-84c3-j8r2-mcm8, inspect your project dependencies using npm:

npm ls @nfid/embed

Analyze the terminal output to locate any version of @nfid/embed in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.10.1-alpha.6), your application is affected.

Note: The npm ls @nfid/embed command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-321: Use of Hard-coded Cryptographic Key, where the product uses a hard-coded, unchangeable cryptographic key. In @nfid/embed, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Problem User sessions in the @nfid/embed SDK with Ed25519 keys are vulnerable due to a compromised private key `535yc-uxytb-gfk7h-tny7p-vjkoe-i4krp-3qmcl-uqfgr-cpgej-yqtjq-rqe`. This exposes users to potential loss of funds on ledgers and unauthorized access to canisters they control. ### Solution Using version >1.0.1 of @dfinity/auth-client and @dfinity/identity packages, or @nfid/embed >0.10.1-alpha.6 includes patched versions of the issue. User sessions will be automatically fixed when they re-authenticate. ### Why this happened The DFINITY auth client library provides a function, `Ed25519KeyIdentity.generate`, for generating an Ed25519 key pair. This function includes an optional parameter to supply a 32-byte seed value, which will be utilized as the secret key. In cases where no seed value is provided, the library is expected to generate the secret key using secure randomness. However, a recent update of DFINITY libraries has compromised this assurance by employing an insecure seed for key pair generation. ### References [AgentJS CVE ](https://github.com/dfinity/agent-js/security/advisories/GHSA-c9vv-fhgv-cjc3)
