CVE-2026-40007 Details
Description
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.
A vulnerability allowing uncontrolled recursion and resource consumption has been identified in Apache IoTDB versions 1.0.0 prior to 2.0.10. When the AirGap receiver is enabled, the 'readLength' method can be exploited by sending repeated E-language prefixes through the socket data. This unbounded recursion can lead to a StackOverflowError, as the recursion depth is not limited, causing the JVM stack to be exhausted.
Users are advised to upgrade to Apache IoTDB version 2.0.10 or later, which addresses this vulnerability.
