Quick assessment

Affected
Gitea Gitea
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.

Gitea 的用户组织列表 API 在未应用单组织端点所强制实施的可见性限制的情况下，为经过身份验证的受限账户返回了“有限可见性”（Limited-visibility）的组织信息。受限用户能够列出已知用户的公开组织成员资格，并获取这些有限可见组织的名称、描述和头像。这导致本应对请求账户隐藏的元数据被泄露。

Vulnerability Title
Gitea restricted-user organization metadata disclosure
Source: CVE Program / CVE List V5
Vulnerability Description
Gitea's user organization-list API includes Limited-visibility organizations for authenticated restricted accounts without applying the visibility restriction enforced by the single-organization endpoint. A restricted user can list a known user's public organization memberships and retrieve limited organizations' names, descriptions, and avatars. This exposes organization metadata that should be hidden from the requesting account.
