Vulnerability Title
QRcode Login for WeChat <= 1.3 - Unauthenticated Account Takeover
Source: CVE Program / CVE List V5
Vulnerability Description
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.

WordPress 授权问题漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
微信二维码登陆是一款基于二维码的身份认证登录方式。 WordPress 微信二维码登陆存在授权问题漏洞，该漏洞源于其未能正确验证微信 Webhook 请求，签名检查始终通过，并且在 Webhook 响应中泄露了生成的登录码。这允许未经认证的攻击者为任意现有用户名伪造登录事件，读取登录码，并通过一个未经认证的 AJAX 操作兑换该码，从而无需密码即以该用户（包括管理员）身份登录。
