Twitter has finally admitted a "Security incident" caused some users' semi-private Twitter Circle tweets to show up on others' timelines.

"In April 2023, a security incident that 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 stated.

The email didn't say why it took the Elon Musk-run biz nearly a month to notify users about the privacy breach - weeks after users started reporting problems with the platform sharing their tweets with the public instead of only family and friends belonging to their Circle.

As the social network explains on its "About Twitter Circle" page: "You choose who's in your Twitter Circle, and only the individuals you've added can reply to and interact with the Tweets you share in the circle."

Also in April: a security researcher spotted a "Shadow ban" vulnerability in the chunk of internal source code that Twitter made public on March 31.

A Twitter user subsequently sued the troubled social media platform over that data leak as lawsuits have also become business as usual under CEO Elon Musk.
