CVE-2026-93363 [MEDIUM] – The @payloadcms/storage-vercel-blob storage adapter for Payload contains an improper acces

The @payloadcms/storage-vercel-blob storage adapter for Payload contains an improper access control vulnerability that allows authenticated users to bypass collection-level permissions by accessing the client-upload route directly. Attackers can upload files through the client-upload endpoint without possessing the required collection access permissions, circumventing the intended access control enforcement.
