How to Fix GHSA-wfm2-rq5g-f8v5

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

@account-kit/smart-contracts fixed: 4.28.2 
npm install @account-kit/smart-contracts@4.28.2
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 @account-kit/smart-contracts

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-wfm2-rq5g-f8v5, inspect your project dependencies using npm:

npm ls @account-kit/smart-contracts

Analyze the terminal output to locate any version of @account kit/smart contracts in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.28.2), your application is affected.

Note: The npm ls @account-kit/smart-contracts command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.
