We are aware of the recently disclosed PHP2Shell vulnerabilities (CVE-2026-109618 and CVE-2026-109619) and can confirm Filestack is not impacted by these vulnerabilities.

Cloud Storage

Cloud storage is where Filestack saves uploaded files. By default this is a storage bucket that Filestack manages in Amazon S3. You can connect your own storage instead.

Supported Providers

  • Amazon S3
  • Azure Blob Storage
  • Google Cloud Storage
  • Dropbox
  • Rackspace

Setup

Add the provider’s access keys in the Developer Portal. For Amazon S3, create a separate IAM user for Filestack with permission to read, write and delete objects in your bucket.

Plan

Storing files in your own cloud storage requires a paid plan.

  • Storage aliases: transform and deliver files already in your storage
  • Upload path and container: choose the folder and bucket for each upload
