CVE-2026-24014 -- CVSS 9.8 Vulnerability Briefing

CVE-2026-24014 | CVSS 9.8 (Critical) | Exploit: No known exploit

What Is It

CVE-2026-24014 is a path traversal vulnerability in Apache IoTDB's DataNode component, specifically in the internal RPC interface responsible for creating Trigger instances.

Technical Detail

The flaw exists because Apache IoTDB DataNode's internal RPC interface accepts a user-supplied Trigger JAR filename and uses it to construct a file system path without adequate input validation, enabling a path traversal attack. An attacker with access to the internal DataNode RPC port can supply a crafted filename containing directory traversal sequences to write or reference arbitrary files on the underlying host. Successful exploitation could lead to remote code execution by placing a malicious JAR in a location where it is subsequently loaded by the application, or to unauthorized file access depending on the deployment context.

Exploitation Status

No known exploit exists for this vulnerability at this time. It is not listed in CISA's Known Exploited Vulnerabilities catalog. There are no public proof-of-concept exploits or reports of active exploitation in the wild as of July 12, 2026.

Who Is Targeting This

No specific threat actor attribution at this time. Neither confirmed nor reported threat actor activity has been associated with this vulnerability.

What To Do

Apply the latest available Apache IoTDB patch addressing this vulnerability as a priority given the critical CVSS score of 9.8. As an immediate workaround, restrict network access to the DataNode internal RPC port using firewall rules or network segmentation so that only trusted internal nodes can reach it, since the attack surface is contingent on that port being reachable. Audit existing IoTDB deployments to confirm whether the internal RPC port is exposed beyond the cluster boundary. Monitor for unexpected JAR files appearing in DataNode directories and review RPC access logs for anomalous Trigger creation requests. Check the Apache IoTDB security advisories page for the specific fixed version and apply it promptly.
