SUMMARYResearchers found that Meta’s Muse AI agent can expose sensitive conversations and shared content through predictable web links. By enumerating share URLs, Claroc said it discovered 6,800 links and opened hundreds that revealed personal and business information not meant for public access. Meta had previously described Muse as built for privacy and security.
Muse, the new general-purpose AI agent from Meta, can expose sensitive information when users share conversations through Web links, researchers reported Monday.
Like many online services, Muse allows users to share searches, conversations, images, and similar content with other people. Such share features usually involve clicking an option to create a unique URL that anyone can use to load a page hosting the content. To keep potentially sensitive information from being accessible to unintended people, the URLs typically contain a long sequence of text that can’t be easily guessed.
A single query is all that's required
Muse, which Meta CEO Mark Zuckerberg said last month was “built from the ground up for privacy and security,” seems to take the same precautions. But a central design decision for constructing URLs has made the links easy to discover. As a result, researchers from security firm Claroc said they were able to enumerate 6,800 links Muse users created for sharing conversations with others. After opening a few hundred of them, the researchers found information that was clearly not intended to be publicly available, including:
