Password Auto-fill Vulnerability in Bitwarden by Bitwarden Inc.

CVE-2023-27974

What is CVE-2023-27974?

Bitwarden versions up to 2023.2.1 exhibit a security flaw where password auto-fill functionality can be triggered on subdomains that match the second-level domain. For instance, if a password is stored for 'example.com', it could automatically fill in on 'customer-website.example.com'. While Bitwarden claims that this feature does not activate by default, it still raises significant concerns regarding user data exposure and phishing attempts. Users should remain vigilant when using auto-fill features, particularly on sites that resemble legitimate services.
