Low risk9th percentile - higher than 9% of all known CVEs
Summary
A vulnerability in Kestra prior to 2.0.0-rc6 exposes 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.
Risk Assessment
An attacker can access sensitive configuration information and change log levels, potentially leading to data leakage or operational disruption.
Recommendation
Update Kestra to version 2.0.0-rc6 or later. Configure authentication for management endpoints or restrict access to port 8081.
Original NVD description (English source)
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.
