Twitter confirms Circle tweets temporarily were not private

Twitter confirmed that a security error that made Circle tweets — posts that only go out to a small subset of trusted friends — surface publicly. TechCrunch reported the glitch in early April, but the platform confirmed the issue today in an email sent to Twitter Circle users.
“In April 2023, a security incident may have allowed users outside of your Twitter Circle to see tweets that should have otherwise been limited to the Circle to which you were posting,” the email said. Twitter claims that the bug has now been fixed, and that the team knows what caused it.
