SCA: security update for litestar (GHSA-3qmc-cj7q-62hv)

medium Tenable Self-Hosted Container Security Plugin ID 443060

Description

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

 - Litestar is an Asynchronous Server Gateway Interface (ASGI) framework. In versions prior to 2.22.0, an
 attacker can bypass the allowed hosts validation by omitting the Host header and supplying an X-Forwarded-
 Host header set to a whitelisted domain. The AllowedHostsMiddleware trusts the X-Forwarded-Host header as
 a fallback when the Host header is absent. Since X-Forwarded-Host is a client-controllable header, this
 enables host header injection attacks such as password reset poisoning, cache poisoning, and server-side
 request routing manipulation. Any application using AllowedHostsConfig is affected when deployed without a
 reverse proxy that strips X-Forwarded-Host, or when accepting HTTP/1.0 connections. This issue has been
 fixed in version 2.22.0. (CVE-2026-48061)

Solution

Update the litestar library and its related packages to version 2.22.0 or later.
