Sharp is a content management framework built for Laravel as a package. Prior to version 9.22.0, Sharp exposes a generic download endpoint that authorizes access only to the supplied Sharp entity instance, but then reads the target storage disk and path from request parameters. Because the requested storage object is not bound to the authorized entity instance, an authenticated Sharp user who can view one valid record may use that record as an authorization anchor to download unrelated disk-relative objects from configured Laravel Storage disks. The confirmed impact is authenticated disclosure of unrelated objects from configured Laravel Storage disks. This issue does not imply arbitrary host filesystem access outside configured Laravel Storage disk roots. This issue has been patched in version 9.22.0.

GHSA-748w-hm6r-qc7v — Authenticated Sharp users can download unrelated Laravel Storage objects through the generic download endpoint

Affected: Packagist: code16/sharp

Sharp exposes a generic download endpoint that authorizes access only to the supplied Sharp entity instance, but then reads the target storage `disk` and `path` from request parameters.

Because the requested storage object is not bound to the authorized entity instance, an authenticated Sharp user who can view one valid record may use that record as an authorization anchor to download unrelated disk-relative objects from configured Laravel Storage disks.

The confirmed impact is authenticated disclosure of unrelated objects from configured Laravel Storage disks. This issue does not imply arbitrary host filesystem access outside configured Laravel Storage disk roots.

### Impact

An authenticated Sharp user with view access to at least one valid Sharp entity instance may be able to download unrelated files from configured Laravel Storage disks by supplying a different `disk` and `path` to the generic download endpoint.

Depending on the application, exposed files may include exports, backups, invoices, internal documents, uploads belonging to other records, tenant-specific data, or operational files stored on private application disks.

The attacker does not need authorization to the storage object being downloaded. They only need an authenticated Sharp session and view access to one valid entity instance that can be used as the authorization anchor.

### Attack requirements

An attacker must have:

- an authenticated Sharp session - view access to at least one valid Sharp e…
