尚无明确在野利用证据，仍需结合暴露面评估
建议动作
优先检查厂商安全公告和参考链接中的修复版本；无法立即升级时，限制受影响服务暴露并加强监测。
Parse Server 是一个开源的后端服务器。在版本 >= 9.0.0 且 < 9.10.1-alpha.10，以及 >= 8.0.2 且 < 8.6.91 中，基于代码的认证适配器（包括 GitHub、Google Play Games、Instagram、LINE、LinkedIn、Microsoft、QQ、Spotify、WeChat、Weibo）在用户注册和绑定外部服务提供商时，会验证客户端提供的授权码，但在登录端点同时提供认证数据（用户名和密码）与外部认证信息时，却未进行验证。 因此，低权限的已认证用

Vulnerability Title
Parse Server 9.0.0 Authentication Bypass via Unverified Provider Identity
来源: CVE Program / CVE List V5
Vulnerability Description
Parse Server is an open-source backend server. In versions >= 9.0.0 < 9.10.1-alpha.10 and >= 8.0.2 < 8.6.91, the code-based authentication adapters (GitHub, Google Play Games, Instagram, LINE, LinkedIn, Microsoft, QQ, Spotify, WeChat, Weibo) verify the client's authorization code with the external provider on signup and on provider linking, but not when authentication data is supplied together with a username and password on the login endpoint. As a result, a low-privileged authenticated user can attach an arbitrary, unverified provider identity to their own account without the provider ever being contacted, spoofing an external identity toward application logic that trusts the linked provider ID. An attacker can also pre-hijack accounts: by claiming the provider ID of a victim who has not yet linked that provider, the victim's later legitimate sign-in with that provider resolves to the attacker's account. Only deployments configuring one of the affected code-based auth adapters are impacted. Versions 9.10.1-alpha.10 and 8.6.91 fix the issue by running the adapter's credential verification on the login and challenge endpoints and rejecting a provider identity already linked to another user. As a workaround, disable the affected code-based auth adapters.
