Collectibles.com, a major collectible cards marketplace, has been leaking sensitive information on hundreds of thousands of users, exposing them to risk of identity theft, wire fraud, phishing, and more, experts have claimed.
Cybernews discovered and reported a non-password-protected Elasticsearch instance containing a 300GB cluster of valuable user data, counting more than 870,000 records.
The exposed data includes users' full names, email addresses, profile picture links, user account details, collectible card sales, and transactional data.
The instance was closed ten days later, but it is unknown for how long it remained open and if any malicious actors accessed the data.
