Vulnerability Title
Potential exposure of Replit tokens to an Unauthorized Actor in @replit/crosis
Vulnerability Description
@replit/crosis is a JavaScript client that speaks Replit's container protocol. A vulnerability that involves exposure of sensitive information exists in versions prior to 7.3.1. When using this library as a way to programmatically communicate with Replit in a standalone fashion, if there are multiple failed attempts to contact Replit through a WebSocket, the library will attempt to communicate using a fallback poll-based proxy. The URL of the proxy has changed, so any communication done to the previous URL could potentially reach a server that is outside of Replit's control and the token used to connect to the Repl could be obtained by an attacker, leading to full compromise of that Repl (not of the account). This was patched in version 7.3.1 by updating the address of the fallback WebSocket polling proxy to the new one. As a workaround, a user may specify the new address for the polling host (`gp-v2.replit.com`) in the `ConnectArgs`. More information about this workaround is available in the GitHub Security Advisory.

Vulnerability Title
crosis 安全漏洞
Vulnerability Description
crosis是提供一个 API 来管理连接（包括断开连接和重新连接）、打开通道以及在通道上发送接收消息/命令的方法。 crosis 存在安全漏洞，该漏洞源于将此库用作以独立方式以编程方式与 Replit 通信的方式时，如果多次尝试通过 WebSocket 联系 Replit 失败，则该库将尝试使用基于回退轮询的代理进行通信。代理的 URL 已更改，因此与前一个 URL 进行的任何通信都可能到达 Replit 控制之外的服务器，并且用于连接到 Repl 的令牌可能被攻击者获取，从而导致该 Repl 的完全破
