Echo: httpcore2: security update to 2.10.0

high Tenable Cloud Security Plugin ID 472226

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - HTTPX2 is a next generation HTTP client for Python. Prior to 2.10.0, httpcore2 fails to start TLS in
 src/httpcore2/httpcore2/_sync/socks_proxy.py and src/httpcore2/httpcore2/_async/socks_proxy.py when the
 remote origin uses wss through a SOCKS5 proxy because the TLS upgrade condition only recognizes https.
 HTTPX2 exposes the flaw through Client.websocket() and AsyncClient.websocket() from 2.6.0 through 2.9.1,
 so the opening handshake, query parameters, Authorization headers, cookies, and subsequent frames can
 cross the proxy path in plaintext without certificate verification. An attacker controlling or observing
 that path can read or modify traffic and impersonate the WebSocket server. This issue is fixed in
 httpcore2 2.10.0 and HTTPX2 2.10.0. (CVE-2026-84381)

Solution

Update the httpcore2 library and its related packages to version 2.10.0 or later.
