Kimai 在 2.58.0 版本之前存在一个身份验证绕过漏洞。该漏洞的原因是密码重置链接在用户更改密码后仍然有效，因为 LoginLink 的签名仅包含用户 ID，而未包含密码哈希值。攻击者若拦截或缓存了某个密码重置链接，可在该链接有效期内（1 小时）再次使用该链接最多两次，即使合法用户已经更改了密码，攻击者仍可借此以该用户身份登录系统。

Vulnerability Title
Kimai before 2.58.0 Authentication Bypass via Password Reset Link
Source: CVE Program / CVE List V5
Vulnerability Description
Kimai before 2.58.0 contains an authentication bypass vulnerability where password reset links remain valid after password changes because the LoginLink signature covers only the user id, not the password hash. Attackers who intercept or cache a password reset link can use it up to 2 additional times within a 1-hour window to log in as the user even after the legitimate user has changed their password.
