| Description | OtterMind Nubase through 0.1.4 contains a missing authentication vulnerability that allows unauthenticated attackers to access private bucket objects because /storage/v1/object/{bucketId}/{path} is treated as public for every HTTP method. Attackers knowing a tenant subdomain, bucket id and object path can download objects from private buckets and delete stored objects without an apikey or JWT. |
