CVE-2026-81027— one-api through 0.6.10 Missing Authorization on URL-Parameter Channel Pinning

Exploitation
Public or AI PoC available; prioritize validation
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

One-API 对其两条“通道固定”（channel-pinning）路径中的其中一条实施了权限管控，而另一条没有。在 中，请求可以通过 API Key 的后缀或 URL 路径参数来指定特定的通道。其中，后缀方式只有在 校验通过后才会被处理，否则会拒绝调用者；而路径参数分支则直接从 取出通道标识，且完全未进行任何角色或权限检查。携带该参数的路由仅处于 Token 认证层之后，因此任何持有有效 API Token 的账户都能访问它。该通道标识随后被传递给分发器（distributor），分发器通过整数标识加载对应通道

Vulnerability Title
one-api through 0.6.10 Missing Authorization on URL-Parameter Channel Pinning
Source: CVE Program / CVE List V5
Vulnerability Description
one-api gates one of its two channel-pinning paths and not the other. middleware/auth.go permits a request to name a specific channel either through a suffix on the API key or through a URL path parameter. The suffix path is reached only after model.IsAdmin succeeds and otherwise rejects the caller, while the path-parameter branch sets the selected-channel value from c.Param("channelid") with no role check at all. The route carrying that parameter sits behind token authentication only, so any account holding a valid API token reaches it. The value flows to the distributor, which loads the channel by integer identifier with no scoping to the caller's user or group, and then sets the outbound Authorization header to that channel's stored key and directs the request at the channel's base URL. A low-privilege account can therefore pin any channel by incrementing an identifier, causing the server to make upstream requests bearing an operator-configured provider key the account was never granted, and bypassing both the per-group restriction and the channel's model allowlist.
