Goobi Viewer 是一款 Web 应用程序，用于在 Web 浏览器中展示数字化资源。在 26.05 版本之前，密码重置令牌的生成基于重置请求的时间，因此具有可预测性。若攻击者知晓目标用户的电子邮件地址，即可发起密码重置请求，随后通过暴力破解获取该令牌。仅利用此漏洞，攻击者即可对任意账户执行未经授权的密码重置。该问题已在 26.05 版本中修复。

Vulnerability Title
Goobi viewer: Predictable Password Reset Token Allows Unauthorized Password Reset
Source: CVE Program / CVE List V5
Vulnerability Description
The Goobi viewer is a web application that allows digitised material to be displayed in a web browser. Prior to version 26.05, the password reset token is predictably based on the time of the reset request. An attacker who knows the target's email address can request a reset and then brute-force the token. Exploiting this finding alone forces an unauthorized password reset on any account. This issue has been patched in version 26.05.
