Descriptions

An issue was discovered by Elastic whereby Elastic Agent would log a raw event in its own logs at the WARN or ERROR level if ingesting that event to Elasticsearch failed with any 4xx HTTP status code except 409 or 429. Depending on the nature of the event that Elastic Agent attempted to ingest, this could lead to the insertion of sensitive or private information in the Elastic Agent logs. Elastic has released 8.11.3 and 7.17.16 that prevents this issue by limiting these types of logs to DEBUG level logging, which is disabled by default.

Elastic descubrió un problema por el cual Elastic Agent registraba un evento sin formato en sus propios registros en el nivel WARN o ERROR si fallaba la ingesta de ese evento en Elasticsearch con cualquier código de estado HTTP 4xx excepto 409 o 429. Dependiendo de la naturaleza del evento, el Agente Elástico intentó ingerir, esto podría llevar a la inserción de información confidencial o privada en los registros del Agente Elástico. Elastic lanzó 8.11.3 y 7.17.16 que evitan este problema al limitar estos tipos de registros al registro de nivel DEBUG, que está deshabilitado de forma predeterminada.
