Twitter's 'security incident' exposes private Circle tweets to public.
Twitter disclosed a security incident that caused private tweets sent to Twitter Circles to show publicly to users outside of the Circle. The incident occurred in April 2023, and Twitter has since fixed the issue. The social site did not disclose the cause of the incident, but it has undergone rapid changes since Elon Musk took ownership, including increasing tweets' exposure via Twitter's recommendation algorithm. Twitter has apologized for the incident and is committed to protecting users' privacy.
