CVE-2026-15368
User Profile Builder – Beautiful User Registration Forms, User Profiles & User Role Editor に報告された脆弱性
概要
The Profile Builder plugin for WordPress is vulnerable to Privilege Escalation in versions up to, and including, 3.16.3. This is due to the target user ID for auto-login after registration being passed as a user-controlled URL parameter (`uid`) with no server-side binding to the issued nonce, allowing any unauthenticated visitor to supply an arbitrary user ID alongside a self-generated valid nonce for the corresponding action. This makes it possible for unauthenticated attackers to log in as any registered user, including administrators, by crafting an autologin URL with an arbitrary user ID, because unauthenticated WordPress nonces have no user binding and the target user ID was supplied entirely via a user-controlled URL parameter.
影響を受けるバージョン
- 3.16.3 以下
対処方法
User Profile Builder – Beautiful User Registration Forms, User Profiles & User Role Editor を 3.16.4 以降に更新してください。これで本脆弱性は解消します。
