@cyclonedx/cdxgen: Docker registry auth substring match forwards credentials to a different registry

GHSA-qhh4-458h-xwh2

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (@cyclonedx/cdxgen 12.3.3), 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.

Docker registry auth substring match forwards credentials to a different registry Repository cdxgen/cdxgen Affected product/package - Ecosystem: npm - Package: @cyclonedx/cdxgen - Reviewed tree version: 12.3.3 - Reviewed commit: b1e179869fd7c6032c3d483c3f7bd4d7154ec22b - Affected file: lib/managers/docker.js - Affected from: v9.9.5 The Single Executable Applications (SEA) binaries and container images are also affected. Weakness CWE-522 / CWE-346. Summary When cdxgen scans or pulls container images through the Docker daemon API, it builds an X-Registry-Auth header from Docker credentials in DOCKERCONFIG/config.json. The credential selection logic matches configured registry keys with substring checks: This is not an origin-safe registry comparison. For example, credentials configured for private-registry.example.com are selected for a requested image under registry.example.com, because: The selected credentials are then serialized into X-Registry-Auth for the Docker API pull request…

# Patch Next advisory brief: GHSA-qhh4-458h-xwh2

Advisory: @cyclonedx/cdxgen: Docker registry auth substring match forwards credentials to a different registry
IDs: GHSA-qhh4-458h-xwh2
Record: https://patchnext.com/advisories/ghsa-qhh4-458h-xwh2 (revision 3, source checked 26 Oct 2026, 12:51 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.9)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: @cyclonedx/cdxgen 12.3.3. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm @cyclonedx/cdxgen: affected >= 9.9.5, < 12.3.3; fixed in 12.3.3

## Suggested inspection (read-only)
- `npm ls @cyclonedx/cdxgen --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 @cyclonedx/cdxgen.
- 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.

## Sources

- Verified: https://github.com/advisories/GHSA-qhh4-458h-xwh2 (GitHub-reviewed advisory GHSA-qhh4-458h-xwh2 lists affected ranges: npm @cyclonedx/cdxgen >=9.9.5 <12.3.3)
