Echo: starlette: security update to 1.0.1

medium Tenable Cloud Security Plugin ID 458157

Description

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

 - Starlette is a lightweight ASGI framework/toolkit. Prior to version 1.0.1, the HTTP `Host` request header
 was not validated before being used to reconstruct `request.url`. Because the routing algorithm relies on
 the raw HTTP path while `request.url` is rebuilt from the `Host` header, a malformed header could make
 `request.url.path` differ from the path that was actually requested. Middleware and endpoints that apply
 security restrictions based on `request.url` (rather than the raw `scope` path) could therefore be
 bypassed. Users should upgrade to a version greater than or equal to version 1.0.1, which validates the
 `Host` header against the grammar of RFC 9112 §3.2 / RFC 3986 §3.2.2 when constructing `request.url` and
 falls back to `scope["server"]` for malformed values. (CVE-2026-48710)

Solution

Update the starlette library and its related packages to version 1.0.1 or later.
