CVE-2026-49989Public exploitNetwork attack vectorHinoki check available

Authenticated blob access via missing HTTP authorization check

Published Aug 14, 2026 · Updated Aug 14, 2026

Incorrect authorization in CrateDB before 6.2.8 and 6.3.0 through 6.3.1 allows remote authenticated users to read, delete, or plant blobs. HttpBlobHandler dispatches GET, HEAD, PUT, and DELETE requests directly to blob operations without consulting AccessControl for table privileges. A reachable BLOB TABLE and valid account are required; reading or deleting an existing blob also requires its SHA-1 digest, while planting a new blob does not.
