Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for hexpm/hexpm, hexpm/hexpm/hexpm.
  2. 2Review the reported fix. Source-reported workaround: * Avoid the local file store backend in any exposed environment. * Restrict network access to the registry when using the local backend. * Production deployments should use object storage (e.g., S3-compatible backends) instead of the local filesystem store.
