Failure to validate signature during handshake

CVE-2022-24759GHSA-j3ff-xp6c-6gcc

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (@chainsafe/libp2p-noise 5.0.3, 4.1.2), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Impact @chainsafe/libp2p-noise before 4.1.2 and 5.0.3 was not correctly validating signatures during the handshake process. This may allow a man-in-the-middle to pose as other peers and get those peers banned. Patches Users should upgrade to 4.1.2 or 5.0.3 Workarounds No workarounds, just patch upgrade References https://github.com/ChainSafe/js-libp2p-noise/pull/130

# Patch Next advisory brief: CVE-2022-24759

Advisory: Failure to validate signature during handshake
IDs: CVE-2022-24759, GHSA-j3ff-xp6c-6gcc
Record: https://patchnext.com/advisories/cve-2022-24759 (revision 2, source checked 26 Oct 2026, 12:16 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: @chainsafe/libp2p-noise 5.0.3, 4.1.2. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm @chainsafe/libp2p-noise: affected < 4.1.2; >= 5.0.0, < 5.0.3; fixed in 4.1.2, 5.0.3

## Suggested inspection (read-only)
- `npm ls @chainsafe/libp2p-noise --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on @chainsafe/libp2p-noise.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
