CVE-2026-59229

Apache IoTDB: Legacy Pipe Privilege Escalation

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.

Apache IoTDB: RPC service denial of service via unchecked Thrift string length

Improper validation of length fields in the Apache IoTDB RPC service may allow a remote unauthenticated attacker to cause a denial of service. By sending a crafted malformed Thrift frame, an attacker can cause IoTDB to allocate an excessive amount of memory and crash with an OutOfMemoryError. This issue affects Apache IoTDB: before 1.3.8, from 2.0.0 before 2.0.9. Users are recommended to upgrade to version 2.0.10, which fixes the issue.

Apache IoTDB: Unauthenticated heap-exhaustion DoS via unbounded allocation in IoTDB AirGap pipe receiver

Memory Allocation with Excessive Size Value, Allocation of Resources Without Limits or Throttling, Missing Authentication for Critical Function vulnerability in Apache IoTDB. When pipe_air_gap_receiver_enabled=true, the IoTDB AirGap pipe receiver accepts raw TCP connections on port 9780 with no authentication. The readLength method reads an attacker-controlled 32-bit integer from the socket and readData passes it directly to new byte[length] with no upper-bound check. An unauthenticated attacker can cause the JVM to attempt an allocation of up to 2,147,483,647 bytes per connection, exhausting heap memory and crashing or severely degrading the DataNode process. This issue affects Apache IoTDB: from 1.0.0 before 2.0.10. Users are recommended to upgrade to version 2.0.10, which fixes the issue.

Apache IoTDB: Unauthenticated unbounded recursion in IoTDB AirGap receiver's E-language prefix parser causes per-connection StackOverflowError

Uncontrolled Recursion, Uncontrolled Resource Consumption vulnerability in Apache IoTDB. When pipe_air_gap_receiver_enabled=true, the IoTDB AirGap receiver's readLength method calls itself recursively each time it recognises the E-language prefix in socket data, with no depth limit. An unauthenticated attacker can send a stream of repeated E-language prefixes that drives the recursion arbitrarily deep, exhausting the receiver thread's JVM stack and raising StackOverflowError. This issue affects Apache IoTDB: from 1.0.0 before 2.0.10. Users are recommended to upgrade to version 2.0.10, which fixes the issue.

This issue affects Apache IoTDB: from 1.0.0 before 2.0.10. Users are recommended to upgrade to version 2.0.10, which fixes the issue.

Apache IoTDB: Authentication Bypass via Forged SessionID in Thrift RPC

Authentication Bypass by Spoofing vulnerability in Apache IoTDB. Certain Thrift RPC query handlers lack strict validation of the sessionId parameter. An attacker can construct requests with a forged sessionId and, without performing openSession authentication, receive valid query results. This allows authentication bypass and unauthorized reading of time-series data. This issue affects Apache IoTDB: from 1.3.3 before 2.0.8. Users are recommended to upgrade to version 2.0.8, which fixes the issue.

Apache IoTDB: Path Traversal in DataNode Internal RPC Trigger JAR Upload Allows Arbitrary File Write

Apache IoTDB DataNode’s internal RPC interface for creating Trigger instances uses the uploaded Trigger JAR name to build a file path without sufficient validation. If the internal DataNode RPC port is exposed to an untrusted network, an attacker may use path traversal sequences in the JAR name to write files outside the intended Trigger installation directory. This could allow arbitrary file write with the permissions of the IoTDB process. This issue affects Apache IoTDB: from 1.3.3 before 2.0.8. Users are recommended to upgrade to version 2.0.8, which fixes the issue.

Apache IoTDB: Denial of Service via Resource Exhaustion in Aggregation Query

Uncontrolled Resource Consumption vulnerability in Apache IoTDB.  Some interface fails to impose reasonable limits on the time span and aggregation interval of the query. An attacker can construct a request with extreme parameters (e.g., a very large time range combined with a minimal interval). This forces the DataNode to build an enormous result set in memory, which exhausts the Java heap and causes the DataNode process to crash. This issue affects Apache IoTDB: from 1.3.3 before 2.0.8. Users are recommended to upgrade to version 2.0.8, which fixes the issue.
