# CVE-2026-24015: Apache IoTDB has an Insecure Default Configuration Vulnerability

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 0.6% , percentile 48: FIRST’s model estimates a 0.6% chance of exploitation activity in the next 30 days, higher than 48% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes org.apache.iotdb:iotdb-core (Maven) >= 1.0.0, < 1.3.7, fixed in 1.3.7 ; org.apache.iotdb:iotdb-core (Maven) >= 2.0.0, < 2.0.7, fixed in 2.0.7 . Check your lockfile, including transitive dependencies.
