Kestra: Unauthenticated management/actuator endpoints exposed on port 8081 (/env, /loggers) bypass API basic-auth
GitHub lists this reviewed advisory for io.kestra:kestra. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.

## Summary Kestra's Micronaut **management endpoints are served on port 8081 with no authentication**, even when the main API (port 8080) has basic-auth enabled. Anyone who can reach `:8081` can read `GET /env` (full resolved environment/configuration) and mutate runtime state via `POST /loggers/{name}` (change log levels), among the other management endpoints. Enabling basic-auth creates a false sense of protection because the auth filter only covers `/api/v1/**` on 8080 and never applies to the 8081 management port. The shipped repository contains no statement that 8081 is management-only / must-not-be-exposed, and the vendor's reference `docker-compose.yml` publishes it with no warning. ## Affected - Product: Kestra (`kestra-io/kestra`), an open-source orchestration/data-pipeline platform (Java / Micronaut). - Version: **v1.3.29** (confirmed); the management-port exposure is an insecure default of the shipped configuration. - No fix at time of report. ## Technical detail Kestra runs the Micronaut management/actuator endpoints on a separate HTTP port **8081**. The authentication filter (basic-auth, when configured) is scoped to the main API on port 8080 (`/api/v1/**`) and does
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.
05 / Provenance
Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
