What happened

The Legacy Pipe receiver protocol (handshake / sendPipeData) uses a hardcoded SUPER_USER (root) identity when executing data loading and deletion operations.

A user with only SYSTEM-level privileges (such as USE_PIPE or MAINTAIN) who does NOT have WRITE_DATA or DELETE_DATA permissions on target databases can send specially crafted PipeData messages through the Legacy Pipe API, resulting in data loading/deletion operations executed as root — effectively bypassing IoTDB's permission model entirely.

This issue affects Apache IoTDB: from 2.0.0 before 2.0.11.

Users are recommended to upgrade to version 2.0.11, which fixes the issue.

About this data

This record was ingested from a data source. Retrieved: Oct 30, 2026, 14:52 UTC. Ingestion is not an independent editorial investigation.

NVD status: Awaiting Analysis. Publication in the NVD is not evidence of exploitation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.

A personal reading checklist on this device, not verified remediation.
