Description

Apache IoTDB versions 0.12.2 through 0.12.6, and 0.13.0 through 0.13.2 are vulnerable to a Denial of Service attack when accepting untrusted patterns for REGEXP queries with Java 8. This issue is patched in 0.13.3. Users should upgrade or use a later version of Java to avoid it.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.iotdb:flink-tsfile-connector, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.apache.iotdb:flink-tsfile-connector to 0.13.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-43766 is resolved across your whole dependency graph.

  3. Workarounds

    Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
