Indiscreet means careless about what should be kept private. An indiscreet remark, indiscreet about it, rather indiscreet.
It charges carelessness rather than malice — an indiscreet person tells what they should not without meaning harm. Note discrete, which is a different word meaning separate, and one of the most frequently confused pairs in English: discreet is tactful and discrete is distinct.
