CVE-2026-28564

A missing authentication for critical function vulnerability exists in Apache IoTDB versions from 2.0.0 before 2.0.11. The flaw may allow unauthorized access to important system functionality.

An authentication bypass vulnerability exists in Apache IoTDB's Thrift RPC service in versions from 2.0.0 before 2.0.11. It may allow an attacker to gain access without valid credentials.

A vulnerability in Apache IoTDB allows remote code execution through unsafe reflection. The pipe processor reads a fully qualified Java class name and instantiates it using Class.forName().newInstance() without any validation or allowlisting.

A Path Traversal vulnerability was found in Apache IoTDB. An attacker can write arbitrary files anywhere the IoTDB process has write permissions using an unsafe API.

The internal RPC interface of Apache IoTDB DataNode 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.

An authentication bypass vulnerability via spoofing has been found in Apache IoTDB. Thrift RPC query handlers do not properly validate the sessionId parameter, allowing an attacker to forge requests and receive query results without authentication. Affected versions are from 1.3.3 before 2.0.8.

A path traversal vulnerability has been discovered in Apache IoTDB, allowing access to files outside the restricted directory. The issue affects versions from 1.0.0 to 1.3.5 and from 2.0.0 to 2.0.6.

A Path Traversal vulnerability has been discovered in Apache IoTDB, allowing bypass of file path restrictions. The issue affects versions from 2.0.0 before 2.0.6 and from 1.0.0 before 1.3.6.

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) but without WRITE_DATA or DELETE_DATA permissions can send crafted PipeData messages to execute operations as root, bypassing IoTDB's permission model.

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. Affects versions before 1.3.8 and from 2.0.0 before 2.0.9. Users are recommended to upgrade to version 2.0.10.
