SCA: security update for astro (GHSA-jrpj-wcv7-9fh9)

medium Tenable Self-Hosted Container Security Plugin ID 443289

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, the spreadAttributes function in Astro's server-side rendering
pipeline iterates over object keys and passes them directly to addAttribute, which interpolates the key
into the HTML output without escaping. When a developer uses the spread syntax {...props} on an HTML
element and the object keys come from an untrusted source (API, CMS, URL parameters), an attacker can
inject arbitrary HTML attributes including event handlers like onmousemove, onclick, or break out of the
attribute context entirely to inject new elements. This vulnerability is fixed in 6.4.6. (CVE-2026-54298)

Solution

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