Prior to 2.0.0-rc6, Kestra's worker/src/main/java/io/kestra/worker/endpoint/WorkerEndpoint.java serves GET /worker without authentication and serializes the complete live Task object, which can expose commands, environment variables, HTTP headers, connection details, plaintext credentials, and execution identifiers while the main API on port 8080 remains protected. This issue is fixed in 2.0.0-rc6."

Antes de la versión 2.0.0-rc6, el archivo worker/src/main/java/io/kestra/worker/endpoint/WorkerEndpoint.java de Kestra sirve GET /worker sin autenticación y serializa el objeto Task completo en vivo, lo que puede exponer comandos, variables de entorno, encabezados HTTP, detalles de conexión, credenciales en texto plano e identificadores de ejecución mientras que la API principal en el puerto 8080 permanece protegida. Este problema se solucionó en la versión 2.0.0-rc6."
