SCA: security update for astro (GHSA-g735-7g2w-hh3f)

medium Tenable Cloud Security Plugin ID 439317

Description

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

 - Astro is a web framework. From version 2.10.10 to before version 5.18.1, this issue concerns Astro's
 remotePatterns path enforcement for remote URLs used by server-side fetchers such as the image
 optimization endpoint. The path matching logic for /* wildcards is unanchored, so a pathname that contains
 the allowed prefix later in the path can still match. As a result, an attacker can fetch paths outside the
 intended allowlisted prefix on an otherwise allowed host. This issue has been patched in version 5.18.1.
 (CVE-2026-33769)

Solution

Update the astro library and its related packages to version 5.18.1 or later.
