Unauthenticated user-data disclosure via unfiltered model serialization
Published Oct 2, 2025 · Updated Oct 2, 2025
Information disclosure in YOSHOP 2.0 allows remote attackers to read sensitive user records through unauthenticated comment-list API calls. The Comment model eagerly serializes its related User model, while User.php defines no hidden or visible field restrictions, placing every loaded user field in the JSON response. No account is required; disclosed data includes bcrypt password hashes, mobile numbers, usernames, and account-balance fields.
