What is CVE-2026-111701?

OtterMind Nubase version 0.1.4 is susceptible to a missing authentication vulnerability that exposes private bucket objects to unauthenticated attackers. This allows malicious actors, who are aware of a tenant subdomain, bucket ID, and object path, to download or delete objects from private buckets without requiring an API key or JWT. The flaw arises from improper access controls within the storage object API, rendering sensitive data vulnerable to unauthorized access.

Affected Version(s)

Nubase 0 <= 0.1.4
