CVE-2026-59229 · Severity: info · Published 2026-10-21

Apache IoTDB is a time-series database used in IoT applications. A flaw in the Legacy Pipe protocol allows users with limited system permissions to execute data operations (loading and deletion) with root-level access by sending specially crafted messages, completely bypassing the database's permission system and potentially exposing or destroying critical data.

## Quick answers

**Is CVE-2026-59229 exploited in the wild?** No. Junglewise Threat Intelligence has no report of CVE-2026-59229 being exploited in the wild.

**How severe is CVE-2026-59229?** Informational severity, published 21 October 2026.

**Which products and versions are affected?** Apache IoTDB 2.0.0 to 2.0.10.

**Is there a fix for CVE-2026-59229?** Yes: fixed in 2.0.11. Junglewise finds every place you run it, drafts the upgrade and applies it once you approve.

**How is CVE-2026-59229 attacked?** It is attacked over the network, in a software library.

**Am I affected by CVE-2026-59229?** Check whether you run Apache IoTDB at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

## How to fix

- Fixed in 2.0.11

## Technical details

The Legacy Pipe receiver protocol (handshake / sendPipeData) uses a hardcoded SUPER_USER (root) identity when executing data loading and deletion operations, allowing users with only SYSTEM-level privileges (such as USE_PIPE or MAINTAIN) to bypass WRITE_DATA and DELETE_DATA permission checks. An attacker can send specially crafted PipeData messages through the Legacy Pipe API to trigger these root-privileged operations. This is a privilege escalation vulnerability affecting the permission model enforcement.

## Affected products

- Apache IoTDB 2.0.0 to 2.0.10

## Timeline
