Authentication Bypass in 微信二维码登陆 (WordPress plugin) (CVE-2026-13597)
Summary
Authentication bypass in 微信二维码登陆 (WordPress plugin) (CVE-2026-13597). Confidential information can be exposed externally.
Original description
The description as published by the source.
The 微信二维码登陆 WordPress plugin through 1.3 does not properly validate WeChat webhook requests, as its signature check always passes, and it discloses the generated login code in the webhook response. This allows an unauthenticated attacker to forge a login event for any existing username, read the login code, and redeem it through an unauthenticated AJAX action to log in as that user, including an administrator, without a password.
