CVE-2026-33359 is an exposure in Meari IoT Cloud alert image storage on Alibaba Object Storage Service (OSS). Motion-alert snapshot images were reportedly stored such that the object URLs acted as direct object references and could be retrieved without authentication, without signed URL protection, and without effective expiration enforcement. The provided context states that image links embedded in MQTT messages remained publicly accessible indefinitely, allowing retrieval of stored motion snapshots outside expected operational windows. In practice, this is an access-control failure over cloud-stored objects, where possession of the object URL is sufficient to fetch sensitive images.
