Quick assessment

Affected
Unknown Temporary Login Without Password
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

版本 1.9.9 之前的 “Temporary Login Without Password” WordPress 插件未阻止临时用户创建应用密码（Application Password），也未在临时访问权限到期或被禁用时撤销该密码，导致临时登录接收者在管理员认为权限已被撤销后，仍能通过 REST 和 XML-RPC 接口继续保有可用的站点访问权限。该保留下来的访问权限携带的是当时被授予的角色，而该插件 1.9.9 之前主要使用场景中授予的角色通常是管理员（Administrator）。

Vulnerability Title
Temporary Login Without Password < 1.9.9 - Authenticated Temporary Access Revocation Bypass via Application Passwords
Source: CVE Program / CVE List V5
Vulnerability Description
The Temporary Login Without Password WordPress plugin before 1.9.9 does not prevent a temporary user from creating an Application Password, and does not revoke one when the temporary access expires or is disabled, allowing the recipient of a temporary login to retain working access to the site over REST and XML-RPC after the administrator believes it has been withdrawn. The retained access carries whatever role was granted, which for the Temporary Login Without Password WordPress plugin before 1.9.9's main use case is Administrator.
