Meta's Muse AI exposed chat titles via URL subdomains

By PulseAugur Editorial · [1 sources] ·

Researchers at Claroc discovered that Meta's Muse AI chat service inadvertently exposed chat titles in URL subdomains, leading to the passive logging of over 6,800 shared links. These exposed links contained sensitive information such as loan applications and executive interview preparations. Meta has since paused sharing features for Muse AI, though Claroc reported no signs of misuse of the exposed data. AI
