Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache IoTDB versions from 1.3.3 before 2.0.8 are vulnerable to uncontrolled resource consumption. The source gives few details on the interface involved. An attacker who can send queries to the DataNode can use extreme time range and aggregation interval parameters to force a large in-memory result set, exhausting the Java heap and crashing the process. Upgrade to version 2.0.8, which fixes the issue.
