Denial Of Service (DoS)

Apache IoTDB is vulnerable to Denial Of Service DoS.The vulnerability is due to missing authentication and insufficient validation of attacker-controlled allocation sizes in the AirGap receiver, allowing unauthenticated attackers to trigger excessive memory allocation and exhaust JVM heap memory,...

Denial Of Service (DoS)

Apache IoTDB is vulnerable to Denial Of Service DoS. The vulnerability is due to uncontrolled recursion in the AirGap receiver's readLength method, where repeated E-language prefixes trigger unbounded recursive calls, allowing unauthenticated attackers to exhaust the JVM stack and cause a...

CVE-2026-40007

Uncontrolled Recursion, Uncontrolled Resource Consumption vulnerability in Apache IoTDB. When pipeairgapreceiverenabled=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 unauthenticate...
