Signed up for Klaviyo? Dozens of advertisers may have seen your password
Klaviyo, a marketing automation platform, exposed user sign-up information including passwords to third-party advertisers due to a website bug. The company inadvertently shared personal data through its interface to external companies during the registration process.
Why it matters: Klaviyo users risk credential compromise and account takeover if attackers obtained passwords shared with third parties; practitioners should prompt affected users to reset credentials immediately.
