Quick assessment

Affected
Thelia Thelia
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Thelia v2.6.0 版本中，管理后台登录接口和“忘记密码”接口针对无效用户名和密码错误分别返回不同的响应，这使得未认证的攻击者能够通过响应差异枚举出有效的管理员账户。此外，由于这些接口缺乏速率限制或其他防止重复身份验证尝试的保护机制，攻击者可以高效地大规模地进行用户名枚举攻击。

Vulnerability Title
CVE-2026-103526
Source: CVE Program / CVE List V5
Vulnerability Description
In Thelia v2.6.0, both the administrative login and forgotten password endpoints return different responses for invalid usernames and incorrect passwords, allowing unauthenticated attackers to enumerate valid administrator accounts. Because the endpoint also lacks rate limiting or other protections against repeated authentication attempts, username enumeration can be performed efficiently at scale.
