How to Fix GHSA-qr2g-p6q7-w82m

To remediate this vulnerability, upgrade all affected @x402/svm dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

@x402/svm fixed: 2.6.0 
npm install @x402/svm@2.6.0
x402 fixed: 2.3.0 
pip install x402>=2.3.0
github.com/coinbase/x402/go fixed: 2.5.0 
Upgrade github.com/coinbase/x402/go to 2.5.0
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 @x402/svm

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-qr2g-p6q7-w82m, inspect your project dependencies using npm:

npm ls @x402/svm

Analyze the terminal output to locate any version of @x402/svm in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.6.0), your application is affected.

Note: The npm ls @x402/svm command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In @x402/svm, 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

### Impact A security vulnerability exists in outdated versions of the x402 SDK. This vulnerability does not affect users' private keys, smart contracts, or funds. The issue impacts resource servers accepting payments on Solana when the facilitator is running a vulnerable version of the x402 SDK. ### Who Should Take Action Facilitators that process payments on Solana must upgrade the x402 SDK to the patched versions listed below. Clients are not required to upgrade. Resource servers are not required to upgrade unless they operate their own facilitator (self-facilitate). ### Patches Please update to the following package versions: * Npm: @x402/svm >= 2.6.0 * Pypi: x402 >= 2.3.0 * Go: x402 >= 2.5.0
