httpcore2 is vulnerable to Cleartext Transmission of Sensitive Information
81
High Risk
This Affects:
httpcore2TL;DR
When routing a secure WebSocket connection through a SOCKS5 proxy, the transport initiates TLS only for https origins and omits wss, so the WebSocket handshake and frames are sent in cleartext to the proxy. Sensitive data such as authorization headers, cookies, and query parameters are sent unencrypted. A malicious or compromised proxy can read or alter credentials and messages, or impersonate the server without certificate verification. The fix initiates TLS for both https and wss origins routed through SOCKS proxies.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you route secure WebSocket (wss) connections through a SOCKS5 proxy.
