CVE-2025-48459: Apache IoTDB Deserialization Of Untrusted Data Vulnerability
CRITICALCVE-2025-48459 is a CRITICAL (CVSS 5.3) deserialization of untrusted data vulnerability (CWE-502: Deserialization of Untrusted Data) affecting Apache IoTDB libraries in the Maven ecosystem. The issue involves deserialization of untrusted data. Remediation is available by upgrading affected packages to version 2.0.5.
CVE-2025-48459 at a Glance
Security Impact
CVSS: 5.3
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N).
How to Fix CVE-2025-48459
To remediate this vulnerability, upgrade all affected Apache IoTDB dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
<dependency>
<groupId>org.apache.iotdb</groupId>
<artifactId>iotdb-confignode</artifactId>
<version>2.0.5</version>
</dependency>pip install apache-iotdb>=2.0.5Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=org.apache.iotdbHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2025-48459, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.apache.iotdbAnalyze the terminal output to locate any version of Apache IoTDB in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.0.5), your application is affected.
Note: The mvn dependency:tree -Dincludes=org.apache.iotdb command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-502: Deserialization of Untrusted Data, where the product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid. In Apache IoTDB, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"details" : "### Summary\n\nApache IoTDB deserializes data from external inputs without sufficient validation, allowing attacker-controlled serialized objects to be processed. In environments where a compatible gadget chain is reachable, this can be abused to execute arbitrary code or alter server state; at minimum it enables high-impact integrity and confidentiality compromise on the IoTDB process.\n\n### Affected\n\nApache IoTDB **from 1.0.0 before 2.0.5**.\n\n### Remediation\n\nUpgrade to **2.0.5**, which addresses the flaw. If immediate upgrade is not possible, restrict exposure of IoTDB endpoints to trusted networks and disable or sanitize any feature paths that accept serialized payloads. These mitigations are defense-in-depth only; upgrading to 2.0.5 is the definitive fix.",
