SCA: security update for astro (GHSA-j687-52p2-xcff)

medium Tenable Cloud Security Plugin ID 440679

Description

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

 - Astro is a web framework. Prior to 6.1.6, the defineScriptVars function in Astro's server-side rendering
 pipeline uses a case-sensitive regex /<\/script>/g to sanitize values injected into inline <script> tags
 via the define:vars directive. HTML parsers close <script> elements case-insensitively and also accept
 whitespace or / before the closing >, allowing an attacker to bypass the sanitization with payloads like
 </Script>, </script >, or </script/> and inject arbitrary HTML/JavaScript. This vulnerability is fixed in
 6.1.6. (CVE-2026-41067)

Solution

Update the astro library and its related packages to version 6.1.6 or later.
