CVE-2026-73245: Kestra: Unauthenticated management/actuator endpoints exposed on port 8081 (/env, /loggers) bypass API basic-auth
Kestra is an open-source, event-driven orchestration platform. Prior to 2.0.0-rc6, Kestra's cli/src/main/resources/application.yml serves Micronaut management endpoints on port 8081 without authentication even when Basic Auth protects /api/v1/ on port 8080, allowing unauthenticated GET /env requests to disclose resolved configuration and POST /loggers/{name} requests to change runtime log levels. This issue is fixed in 2.0.0-rc6.
