CVE-2025-12148

In Search Guard versions 3.1.1 and earlier, Field Masking (FM) rules are improperly enforced on fields of type IP (IP Address). While the content of these fields is properly redacted in the _source document returned by search operations, the results do return documents (hits) when searching based on a specific IP values. This allows to reconstruct the original contents of the field. Workaround - If you cannot upgrade immediately, you can avoid the problem by using field level security (FLS) protection on fields of the affected types instead of field masking.

Type	Values Removed	Values Added
Summary		(es) En las versiones 3.1.1 y anteriores de Search Guard, las reglas de enmascaramiento de campos (FM) se aplican incorrectamente en campos de tipo IP (dirección IP). Si bien el contenido de estos campos se redacta correctamente en el documento _source devuelto por las operaciones de búsqueda, los resultados sí devuelven documentos (hits) al buscar basándose en valores IP específicos. Esto permite reconstruir el contenido original del campo. Solución alternativa - Si no puede actualizar de inmediato, puede evitar el problema utilizando protección de seguridad a nivel de campo (FLS) en campos de los tipos afectados en lugar de enmascaramiento de campos.
