Plane 是一个开源的项目管理工具。在版本 1.4.0 之前，如果通过将 is_active 字段设置为 False 而停用（deactivate）了某个用户账户，该用户仍可以使用其已有的凭据登录。成功登录后，系统会自动将 is_active 重新设为 True，从而静默地重新激活该账户，而不会通知管理员。此问题已在 1.4.0 版本中修复。

Vulnerability Title
Plane: Disabled User Auto-Reactivation on Login
Source: CVE Program / CVE List V5
Vulnerability Description
Plane is an open-source project management tool. Prior to 1.4.0, a user whose account has been deactivated by setting is_active=False can still log in with existing credentials. Successful authentication silently changes is_active back to True, reactivating the account without notifying the administrator. This issue is fixed in 1.4.0.
