SCA: security update for astro (GHSA-7pw4-f3q4-r2p2)

low Tenable Cloud Security Plugin ID 445921

Description

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

 - Astro is a web framework for content-driven websites. In versions 3.10.0 through 7.0.3, when a
 transition:persist, transition:scope, or transition:persist-props directive is applied to a client-
 hydrated (client:*) component, Astro copied the directive value onto the rendered <astro-island> element
 without HTML-escaping it. If a developer reflects attacker-controlled input into one of these directives,
 an attacker can break out of the attribute and inject arbitrary HTML/JavaScript into the server-rendered
 output, resulting in reflected cross-site scripting (XSS). Exploitation requires the application developer
 to have written a non-idiomatic pattern — passing untrusted, request-derived input directly into a
 transition directive. Astro applications that do not route untrusted input into these directives are
 unaffected. This issue has been fixed in version 7.0.4. (CVE-2026-59727)

Solution

Update the astro library and its related packages to version 7.0.4 or later.
