Description

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A security vulnerability exists in outdated versions of the x402 SDK.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

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/coinbase/x402/go. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update github.com/coinbase/x402/go to 2.5.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-qr2g-p6q7-w82m is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 pinpoints whether GHSA-qr2g-p6q7-w82m is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-qr2g-p6q7-w82m. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
