CVE-2026-7567
Temporary Login <= 1.0.0 - Authentication Bypass to Account Takeover

Description
The Temporary Login plugin for WordPress is vulnerable to Authentication Bypass in versions up to and including 1.0.0. This is due to improper input validation in the maybe_login_temporary_user() function, which fails to verify that the 'temp-login-token' GET parameter is a scalar string before processing it. When the parameter is supplied as an array, PHP's empty() check is bypassed and sanitize_key() returns an empty string, which is then passed as the meta_value to get_users(). WordPress ignores an empty meta_value and returns all users matching the meta_key '_temporary_login_token', allowing authentication without a valid token. This makes it possible for unauthenticated attackers to authenticate as any active temporary login user by sending a single crafted GET request.
