Vulnerability from cvelistv5 – Published: 2026-07-10 07:12 – Updated: 2026-07-10 14:54

Title

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

Summary

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.

Severity

7.5 (High)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
