在 Pingvin Share X 1.22.0 之前的版本中存在一个无效的速率限制漏洞，原因是以秒为单位指定的限速器 TTL（Time-To-Live）值被错误地解释为毫秒。未授权的攻击者可以向 /api/auth/signIn、/api/auth/signIn/totp 和 /api/auth/resetPassword 接口发送几乎不受限的请求，从而对密码和 TOTP 代码进行暴力破解。

Vulnerability Title
Pingvin Share X before 1.22.0 Ineffective Authentication Rate Limiting via Throttler TTL
Source: CVE Program / CVE List V5
Vulnerability Description
Pingvin Share X before 1.22.0 contains an ineffective rate limiting vulnerability because throttler TTL values specified in seconds are interpreted as milliseconds. Unauthenticated attackers can send effectively unthrottled requests to /api/auth/signIn, /api/auth/signIn/totp and /api/auth/resetPassword to brute-force passwords and TOTP codes.
