SCA: security update for astro (GHSA-2pvr-wf23-7pc7)

high Tenable Self-Hosted Container Security Plugin ID 443290

Description

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

 - Astro is a web framework. Prior to 6.4.6, Astro SSR apps with prerendered error pages (/404 or /500 using
 export const prerender = true) fetch those pages over HTTP at runtime when an error occurs. The URL for
 this fetch is derived from request.url, which in turn gets its origin from the incoming Host header. When
 the Host header is not validated against allowedDomains, an attacker can point the fetch at an arbitrary
 host and read the response. This vulnerability is fixed in 6.4.6. (CVE-2026-54299)

Solution

Update the astro library and its related packages to version 6.4.6 or later.
