Blabbermouth

A blabbermouth is an individual, typically prone to excessive and indiscreet talk, who divulges secrets, reveals sensitive information, or simply talks excessively about trivial matters.

Their behavior can be socially disruptive, leading to embarrassment, damaged relationships, or the exposure of information that was meant to remain confidential. The term implies a casual and often thoughtless disregard for others' privacy.
