CVE-2026-33221

Nhost Storage Affected by MIME Type Spoofing via Trusted Client Content-Type Header in Storage Upload PUBLISHED

Description (CNA)

Nhost is an open source Firebase alternative with GraphQL. Prior to version 0.12.0, the storage service's file upload handler trusts the client-provided Content-Type header without performing server-side MIME type detection. This allows an attacker to upload files with an arbitrary MIME type, bypassing any MIME-type-based restrictions configured on storage buckets. This issue has been patched in version 0.12.0.
