CVE-2026-111701 · OtterMind Nubase through 0.1.4 Missing Authentication in Storage Object API
This page contains facts from public vulnerability sources. Check the original advisory before updating.
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.
